Bug and Known Problem List
No.143 Invalid RTCM MSM message generation with wrong number of Cell-mask (STRSVR, STR2STR)
In case of (number of satellites) x (number of signals) exceeds 64, invalid RTCM MSM messages with wrong number of Cell-mask are generated by the RTCM 3 encoder.
Due to a bug on the RTCM MSM encoder rtlib/src/rtcm3e.c. The (number of satellites) x (number of signals) should not exceed 64 in a RTCM MSM message as defined as RTCM 3.2 or 3.3 (126.96.36.199). In this case, the messages should be separeted to multiple ones. It will be fixed in the next release. (2018/10/22)
No.142 GMView (Google Map View) of RTKPLOT is not properly shown (RTKPLOT)
GMView (Google Map View) of RTKPLOT is not properly shown. GMView shows a warning dialog and a dark map screen with messages "For development purposes only".
Due to the Google policy change to keyless usage of the Google Maps API. After June 11, 2018, the usage of Google Maps API always needs the API key (ref). If you want to use GMView, please obtain your own API Key by yourself and edit the header line of the GMView HTML file rtklib/bin/rtklplot_gm.htm as follows. (2018/09/26)
No.141 Unable to handle data of Galileo E31 - E36 satellites (RTKPLOT, RTKCONV, RTKNAVI, RTKPOST, CONVBIN, RTKRCV, RNX2RTKP ver.2.4.2)
Data of Galileo E31 - E36 satellites can not be handled. Observation and navigation data for these satellites are rejected as having invalid PRN number.
PRN 1 - 36 (E1B/C, E5a, E5b) are assigned to the Galileo satellites according to Galileo OS-SIS-ICD 3.6. However, the current definition of maximum PRN number of Galileo in RTKLIB is 30 as the constant MAXPRNGAL. Galileo PRN 31 - 36 are recognized as invalid PRN number and rejected. It will be fixed in the next patch. Until the release, modify the following source code and rebuild APs. (2018/07/30)
#define MAXPRNGAL 30 /* max satellite PRN number of Galileo */
#define MAXPRNGAL 36 /* max satellite PRN number of Galileo */
No.140 RTCM 3 MSM generated by STRSVR or STR2STR is not recognized (STRSVR, STR2STR)
RTCM 3 MSM messages (RTCM MT 107x, 108x, 109x, 110x, 111x and 112x) generated by STRSVR or STR2STR with Conversion option (receiver raw -> RTCM 3) are not recognized in some rover receivers.
Due to a bug on encoding the lock time field in the RTCM MSM messages by the RTCM 3 encoder rtklib/src/rtcm3e.c. Inproper lock time filed makes a trouble to recognize the RTCM MSM messages. It is fixed in the patch rtklib_2.4.2_p13 (source, binary). (2018/01/29).
No.139 GMView (Google Map View) of RTKPLOT does not work (RTKPLOT)

- Data: 11000 (decimal)
No.138 Galileo E30 satellite is not trackable and usable (RTKPLOT, RTCONV, CONVBIN, RTKNAVI, RTKRCV ver.2.4.2)
Galileo E30 satellite is not trackable and usable. There is no satellite in the skyplot.
The maximum PRN number of Galileo satellites was set to 27 as MAXPRNGAL in rtklib/rtklib.h. It is fixed in the patch rtklib_2.4.2_p13 (source, binary). (2018/01/29)
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 is fixed in the patch rtklib_2.4.2_p13 (source, binary).(2018/01/29)
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 patch rtklib_2.4.2_p13 (source, binary). (2018/01/29)
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 is fixed in the patch rtklib_2.4.2_p13 (source, binary). (2018/01/29)
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 is fixed in the patch rtklib_2.4.2_p13 (source, binary). (2018/01/29)
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 is fixed in the patch rtklib_2.4.2_p13 (source, binary). (2018/01/29)
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.

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)

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.

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.

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).
