Issues or Pull Requests for the GitHub repository may provide helpful info.
The beta versions of RTKLIB are available as a development branch of the GitHub repository.

Bug and Known Problem List

No.137 Invalid decoding of signed 1-byte fields in raw receiver data by ARM-GCC (RTKCONV, CONVBIN, RTKNAVI, RTKRCV, STRSVR, STR2STR ver. 2.4.2)

Signed 1-byte binary fields in raw receiver data are not properly decoded in ARM-GCC environment.
Some codes imply "char" as "signed char". However, whether "char" as "signed char" or as "unsigned char" is machine-dependent. In ARM-GCC environment, "char" is recognized as "unsigned char" as default. Invalid sign decoding of the field leads improper value. It will be fixed in the future release. Until the release, add the compiler option to makefile in order to change the default behaviour. For ARM-GCC, use the option -fsigned-char. (2017/04/11)

No.136 GEView (Google Earth View) of RTKPLOT does not work (RTKPLOT)

GEView (Google Earth View) of RTKPLOT does not work. RTKPLOT shows only a blank plot.
GEView uses Google Earth API provided by Google. The Google Earth API is terminated on January 11, 2017 (reference). There is no way to support GEView without the Google Earth API. (2017/01/26)

No.135 The leap second before 2017/01/01 00:00:00 UTC is not involved (All ver. 2.4.2 p11)

The leap second before 2017/01/01 00:00:00 UTC (2016/12/31 23:59:60 UTC) is not involved. Some problems might arise by the leap second insertion after 2017/01/01 00:00:00 UTC especially on GLONASS data handling.
Due to the lack of the record in the hard-coded leap second table in rtklib/src/rtkcmn.c. It is fixed in the patch 2.4.2 p12. Refer GitHub (source, binary) for the patch. (2017/01/03)

No.134 Loss-of-lock status is not recognized in RTCM MSM 6 or 7 (RTKCONV, CONVBIN, RTKNAVI, RTKRCV ver. 2.4.2)

The loss-of-lock or cycle-slip status is not recognized in RTCM MSM 6 or 7.
Due to a bug of rtklib/src/rtcm3.c. The field size of the lock-time in RTCM MSM 6 or 7 is 10 bits. However, the previous lock-time value is saved in 8-bit unsigned int in rtcm_t struct. The cycle-slip is unable to be catched in case of reversal of the lock-time.
It will be fixed in the next release. Until the release, modify the code rtklib/src/rtklib.h L906-907 as follows and rebuild APs. (2016/08/20)
unsigned char lock[MAXSAT][NFREQ+NEXOBS]; /* lock time */
unsigned char loss[MAXSAT][NFREQ+NEXOBS]; /* loss of lock count */
unsigned short lock[MAXSAT][NFREQ+NEXOBS]; /* lock time */
unsigned short loss[MAXSAT][NFREQ+NEXOBS]; /* loss of lock count */

No.133 Potential carrier-phase range overflow or underflow in RTCM MT1001-1004, 1009-1012 (STRSVR, STR2STR ver. 2.4.2)

The PhaseRange-Pseudorange fields in RTCM MT 1001-1004, 1009-1012 (DF012, DF018, DF042, DF048) generated by RTKLIB could overflow or underflow the range. The rollover is handled at +-1500.0 cycle in rtklib/src/rtcm3e.c cp_pr() but the +-1500.0 cycle corresponds to +-285.44m (GPS L1) and +-366.32m (GPS L2), which are out of the proper range (+-262.14m). The problem may cause the invalid carrier-phase value where the RTCM message received.
It will be fixed in the next release. Until the release, modify the code rtklib/src/rtcm3e.c L194 as follows and rebuild APs. (2016/06/29)
return fmod(cp-pr_cyc+1500.0,3000.0)-1500.0;
return fmod(cp-pr_cyc+750.0,1500.0)-750.0;

No.132 UBX-TRK-MEAS and UBX-TRK-SFRBX are no longer available by u-blox M8N F/W 3.01

Unofficial raw-messages UBX-TRK-MEAS (0x03 0x10) and UBX-TRK-SFRBX (0x03 0x0F) are no longer available by u-blox M8N F/W 3.01. The command file data/ubx_m8n_glo_raw_1hz.cmd and data/ubx_m8n_bds_raw_1hz.cmd don't work properly for M8N F/W 3.01. (2016/01/30)

No.131 The code of L2C in RTCM MT1004 is not properly recognized (RTKCONV, CONVBIN ver.2.4.2)

By RINEX conversion, the code of L2C in RTCM MT1004 messages is not properly recognized. For RINEX 3, the L2C data are decoded as "2C" (L2C/A). For RINEX 2, the L2C pseudorange data vanish in RINEX by misinterpretation of the code.
It will be fixed in the next release. Until the release, modify the code rtklib/src/rtcm3.c L302 as follows and rebuild APs. (2016/01/16)
const int L2codes[]={CODE_L2C,CODE_L2P,CODE_L2W,CODE_L2W};
const int L2codes[]={CODE_L2X,CODE_L2P,CODE_L2D,CODE_L2W};

No.130 NVS receiver's measurement data is not recognized on ARM CPU (RTKRCV, STR2STR ver.2.4.2)

NVS receiver's data is not recognized on an ARM CPU board (BeagleBone etc).
In the NVS driver, the time-tag in the xf5-raw measurement data message is checked by comparing with the previous message's time-tag in order to reject wrong data. The first message is compared with the CPU time. If the difference of the first time-tag from the CPU time is more than 1 day, all messages are discarded. It will be fixed in the next release. Until the release, (1) Set the CPU time to the proper time or (2) comment out rtklib/src/rcv/nvs.c L116-120 and rebuild RTKRCV/STR2STR. (2015/12/19)

No.129 Bus error on ARM with RTKRCV or STR2STR by decoding Javad (RTKRCV, STR2STR ver.2.4.2)

Bus error occures by RTKRCV or STR2STR on an ARM processor by decoding the Javad steram.
Due to a byte-boundary limitation of a multiple-byte-word on ARM. It may not occure on x86 environment. It will be fixed in the next release. Unitl the release, modify the code rtklib/src/rcv/javad.c (L50) as follows and rebulid APs. (2015/08/09)
static float R4(unsigned char *p)
    if (U4(p)==0x7FC00000) return 0.0f; /* quiet nan */
    return *(float*)p;

    return value;

No.128 A minor bug on displacement computation by OTL (RTKPOST, RNX2RTKP, RTKNAVI, RTKRCV ver.2.4.2)

The station displacement by OTL (ocean tide loading) for PPP has a following minor bug. (src/ppp.c L241) The effect of the bug rearches 1 cm as horizontal and 2 cm as vertical of PPP-kinematic solutions.
(wrong) days=timediff(epoch2time(ep),epoch2time(ep1975))/86400.0;
(correct) days=timediff(epoch2time(ep),epoch2time(ep1975))/86400.0+1.0;
It will be fixed in next release. (2015/06/11)

No.127 Rejection of RTCM SSR messages by IOD inconsistency between orbit and clock correction (RTKPOST, RTKNAVI, RNX2RTKP and RTKRCV ver.2.4.2)

With "Broadcast+SSR APC" or "Broadcast+SSR CoM" as the "Satellite Ephemeris/Clock" option typically in PPP-modes, input RTCM SSR messages are frequently rejected by IOD inconsistency error. The warning message "inconsist ssr correction: ..." is found in the debug trace file.
Due to bugs in rtklib/src/postpos.c and rtklib/src/rtksvr.c. They will be fixed in the next release. (2015/4/29)

No.125 Invalid ionosphere correction for GLONASS or BeiDou in "SINGLE" and "PPP" modes (RTKPOST, RNX2RTKP, RTKNAVI, RTKRCV ver.2.4.2 p10)

In case of "SINGLE", "PPP-STATIC","PPP-KINEMATIC","PPP-FIXED" and the "ionosphere correction" option set to "Broadcast", "SBAS", "IONEX TEC", "QZSS Broadcast" or "QZSS LEX", the ionosphere correction for pseudorange and carrier-phase for GLONASS or BeiDou satellites is invalid. The frequency difference between GPS L1 and GLONASS L1/BeiDou B1 should be taken into account for the correction.
Due to bugs in rtklib/src/pntpos.c, ppp.c. Apply the patch rtklib_2.4.2_p11.zip. (2015/03/23)

No.124 Invalid pole tide correction due to incorrect ERP interpolation (RTKPOST, RNX2RTKP ver.2.4.2 p10)

No.118 AR performance of baseline processing degraded by unhealthy satellites (RTKNAVI, RTKPOST, RTKRCV, RNX2RTKP ver. 2.4.2)

AR (ambiguity resolution) performance is degraded if unhealthy satellites are incorpolated in baseline processing.
Due to a bug in rtklib/src/rtkpos.c. The ambiguities for unhealthy satellites, which should be excluded, are involved in the AR process. Apply the patch rtklib_2.4.2_p10.zip. (2014/11/8)

No.117 GLONASS ephemerides are not properly read from a RTCM stream without obsevation data (RTKNAVI, RTKRCV, STRSVR, STR2STR ver. 2.4.2)

GLONASS ephemerides (MT 1020) are not properly read from a RTCM stream without observation data. For example, the problem appears in case of using the IGS-RTS RTCM3EPH stream.
RTKLIB uses the time in observation data to solve the day ambiguity for tk or tb in GLONASS ephemerides. Without such information, RTKLIB initially uses CPU time but the time is not updated in the long operation of the input stream. After the vaild time expired in 1 day, invalid ephmemerides with wrong tk or tb values are read. Apply the patch rtklib_2.4.2_p10.zip. (2014/11/8)

No.116 No support of local or non-standard extensions for RINEX 2 (RTKPOST, RTKCONV, RNX2RTKP, CONVBIN ver.2.4.2)

RTKLIB does not support the following local or non-standard RINEX extensions.
- RINEX "2.11 extended" by UNAVCO TEQC (reference).
- RINEX 2.11 extensions for Galileo, QZSS and BeiDou navigation data.
- RINEX 2.12 extensions for BeiDou navigation data
The only supported extension is "RINEX 2.12 QZSS extension" by JAXA. (reference)
These non-standard RINEX files cannot be properly read by RTKLIB APs. (2014/9/8)

No.115 Input stream error "get comconfig error (87)" over Bluetooth virtual COM port (RTKNAVI, STRSVR ver.2.4.2)

Over a virtual COM port by Bluetooth SPP (serial port profile), RTKNAVI or STRSVR sometimes fails to start by the error "get comconfig error (87)". The "(87)" means Windows error code #87 "ERROR_INVALID_PARAMETER". Refer the topic for additional information (in Germany).
Apply the patch rtklib_2.4.3_p10.zip. (2014/11/8)

No.114 Invalid format of saved image by RTKPLOT (RTKPLOT ver.2.4.2)

Even if selecting JPEG as the format by the menu "Edit" - "Save Image...", RTKPLOT saves the image not as JPEG but as Windows BMP.
Due to a bug in app/rtkplot/plotmain.cpp. Apply the patch rtklib_2.4.2_p10.zip. (2014/11/8)

No.113 Invalid identification of obs type "C2" in RINEX 2.11 or 2.12 (RTKPOST, RNX2RTKP, RTKCONV, CONVBIN ver. 2.4.2 p9)

The obs type "C2" of GPS in RINEX 2.11 or 2.12 is recognized as "C2W" (L2 Z-tracking) as RINEX 3. It shuould be "C2S", "C2L" or "C2X" (L2C) in RINEX 2.11 and "C2D" (C/A + (P2-P1)) in RINEX 2.12.
Due to a bug in src/rinex.c to convert RINEX 2 obs codes to RINEX 3. "C2" in RINEX 2.11 is recognized as "C2X". "C2" in RINEX 2.12 is recognized as "C2W". Apply the patch rtklib_2.4.2_p10.zip. (2014/11/8)

No.111 Improper decoding of GLONASS ephemeris IODE in JAVAD [NE] (RTKNAV, RTKRCV, RTKCONV, CONVBIN ver.2.4.2)

Improper decoding of the GLONASS ephemeris IODE in JAVAD [NE]. IODE 64 - 127 are output as wrong value 0 - 63. No problem for IODE 0 - 63. IODE is usually used to determine corresponding ephemeris for RTCM SSR correction. GLONASS satellites are often unavailable caused by wrong IODE for JAVAD stream.
Due to a bug in src/rcv/javad.c. Apply the patch rtklib_2.4.2_p9.zip. (2014/8/27)

No.110 No swap function of solution status files for RTKNAVI or RTKRCV (RTKNAVI, RTKRCV ver.2.4.2)

In case of continous operation of RTKNAVI or RTKRCV, the size of the solution status file increases too largely. It is not easy to handle such large-size files. It is desireble to separate it into muliple files.
There is no function to swap such the solution status file. Apply the patch rtklib_2.4.2_p9.zip. (2014/8/27)

No.109 CPU overload with abnormal telnet shutdown on the RTKRCV command console (RTKRCV ver.2.4.2)

With abnormal telnet shutdown on the RTKRCV command console, an infinite input loop causes CPU overload. It is not able to login from another console as well.
Due to a bug in rtklib/app/rtkrcv/rtkrcv.c. Apply the patch rtklib_2.4.9_p9.zip. (2014/08/27)

No.108 Unable to read u-blox UBX-RXMRAW messages (RTKNAVI, RTKRCV, RTKCONV, CONVBIN, STRSVR, STR2STR ver. 2.4.2 p8)

UBX-RXMRAW messages are unable to read from u-blox receiver streams if the stream contains UBX-NAVSOL or UBX-NAVTIME.

No.106 Restriction of the visible satellite number for baseline processing (RTKPOST, RNX2RTKP, RTKNAVI, RTKRCV ver. 2.4.2 p7)

In baseline processing cases including "Kinematic" or "Static", the number of visible satellite over 32 might have a trouble. Some satellites cannot be used to get solutions.
The constant MAXOBS is defined in rtklib/src/rtklib.h as 64. The sum of the visible satelite numbers in both rover and base-station sides should be below MAXOBS. If the number exceeds MAXOBS, the remains are discarded.
Appy the patch rtklib_2.4.2_p8.zip.

No.105 A memory exception in reading RINEX 2 obs data (RTKPOST, RTKPLOT, RNX2RTKP, RTKCONV, CONVBIN ver.2.4.2 p6)

In case of reading RINEX 2 observation data, a memory exception aborts the APs.
Due to a bug in rtklib_2.4.2_p6.zip. Not-terminated obs code table causes a memory access violation in obs2code(). Apply the patch rtklib_2.4.2_p7.zip. All modifications by rtklib_2.4.2_p5 and rtklib_2.4.2_p6 are included in the patch. (2014/05/29)

No.104 A memory exception in a baseline analysis with triple-frequency+GPS+GLO+BDS (RTKPOST, RTKNAVI, RNX2RTKP, RTKRCV ver.2.4.2 p6)

No.102 Unable to incorporate BeiDou satellites in post-processing and real-time solutions (RTKPOST, RTKNAVI, RNX2RTKP, RTKRCV ver.2.4.2)

BeiDou satellites are not incorporated in post-processing and real-time solutions even with BeiDou enabled.
In ver.2.4.2, BeiDou is not yet supported for post-processing and real-time solutions. RTKLIB can handle BeiDou data only for convert and plot. To enable solutions with BeiDou, apply the patch rtklib_2.4.2_p7.zip. (2014/05/29)

No.101 Unable recovery of a NTIRP connection down by an inactive timeout (STRSVR, STR2STR, RTKNAVI, RTKRCV ver.2.4.2)

After an inactive timeout of a NTRIP connection, RTKLIB tries to re-connect to the NTRIP caster. If a temporal DNS timeout occures in the re-connection process, the NTRIP connection can never be restored as an error-state. In this case, users have to stop and re-start the APs to recover the connection.
Due to a problem in rtklib/src/stream.c. Apply the patch rtklib_2.4.2_p7.zip. (2014/05/29)

No.100 Unable Multipath-Elevation Plot without SNR data (RTKPLOT ver.2.4.2)

Without SNR data in RINEX OBS files, it is not able to generate the Multipath - Elevation plot.
Due to a bug in rtklib/app/rtkplot/rtkdraw.cpp. Apply the patch rtklib_2.4.2_p7.zip. (2014/05/29)

No.99 Dropping the last field of RTCM 3 SSR messages (RTKNAVI, RTKRCV ver.2.4.2)

The last correction field of RTCM 3 SSR messages could be dropped in some cases. The orbit and clock corrections for the last satellite in a message might not be properly applied in PPP cases.
Due to a bug in rtklib/src/rtcm3.c. Apply the patch rtklib_2.4.2_p7.zip. (2014/05/29)

No.98 Invalid IODE field in decoded BINEX 0x01-02 messages (GLONASS ephemeris) (RTKNAVI, RTKRCV ver.2.4.2)

The IODE field in decoded BINEX 0x01-02 messages (GLONASS ephemeris) is invalid. The SSR orbit and clock corrections for GLONASS is not properly applied to BINEX input data stream by the IODE incompatibility problem.
Apply the patch rtklib_2.4.2_p7.zip. (2014/05/29)

No.97 Invalid satellite antenna offset correction for PPP (RTKNAVI, RTKPOST, RTKRCV, RNX2RTKP ver.2.4.2)

The satellite antenna offset for PPP is based on only the L1 value. The antnena phase center should be the iono-free LC position of L1 and L2 offsets. If the L1 and L2 offsets are different, it is not properly corrected. Note that IGS08.ATX has no problem because all of L1 and L2 offset for GPS and GLONASS have the same values.
Apply the patch rtklib_2.4.2_p7.zip. (2014/05/29)

No.96 Not compliant to RINEX 3.02 for BeiDou observation codes (RTKPLOT, RTKCONV, CONVBIN ver.2.4.2)

The current RTKLIB is based on RINEX 3.02 draft (December 10, 2012) in which the BeiDou B1 signal is represented as C2, L2, D2 and S2. The final RINEX 3.02 (April 3, 2013) defines the observation codes for BeiDou B1 as C1, L1, D1 and S1, which were changed from the draft. So RTKLIB cannot handle the observation codes of BeiDou C1, L1, D1 and S1 in the final RINEX 3.02.
Apply the patch rtklib_2.4.2_p7.zip. (2014/05/29)

No.88 Unable playback of log file with time-tags in 64-bit environement (STR2STR, RTKRCV ver. 2.4.2)

A Log file with time-tags cannot be properly playbacked by STR2STR or RTKRCV which is built in 64-bit environment.
Due to a bug in src/stream.c. File pointers in the time-tag file is not properly read because the program assumes 32-bit pointers. It does not affect to 32-bit APs. Windows binary APs included in the RTKLIB package also have no problem. The patch will be released. Apply the patch rtklib_2.4.2_p3.zip. (2013/06/02)

No.87 Invalid read of RTCM MSM stream with BeiDou data (RTKNAV, RTKCONV, STRSVR, CONVBIN, STR2STR ver.2.4.2)

If a RTCM MSM stream contains BeiDou measurement data, the time-tag indicates 14s offset. The MSM messages for other navigation systems are not able to be read in this case.
The current version assumes the epoch time of BeiDou MSM messages based on GPST. If the epoch time is based on BDT, the time offset of 14s between GPST and BDT induces invalid data read of MSM stream. Apply the patch rtklib_2.4.2_p3.zip. (2013/06/02)

No.86 Unable automatic update of real-time solution plot after the real-time buffer full. (RTKPLOT ver.2.4.2)

How to apply a patch

(1) Extract zip file of the patch. Copy and overwrite it to the AP(s) and source program(s) in RTKLIB directory.
(2) From ver.2.3.0, all the patches include the executable binary AP(s) for Windows as well as source program(s). So usually you do not need to rebuild AP on Windows. If you want to build AP by yourself, try the following procedure.
(a) Execute Embarcadero C++ builder (http://www.embarcadero.com). Open the project file (*.cbproj) in the application program directory (rtklib_<ver>\app\<ap>) and rebuild the application program. For details, refere the manual 2.1 and 4.1.
(b) Execute install.bat in the application program directory. It copies the new program to the directory of binaries (rtklib_<ver>\bin).
