Bug and Known Problem List

No.30 Inverted Polarity of Doppler Frequency in NovAtel OEM3 REGD (RTKNAVI, RTKCONV, CONVBIN ver.2.2.2)

The polarity of Doppler frequency in NovAtel OEM3 REGD messages is recognized in inverted manner. The D1 and D2 in RINEX OBS files converted by RTKCONV or CONVBIN for NovAtel OEM3 show improper values.

Due to the bug in rcv/novatel.c. Wait for the next version to fix the bug. (2009/12/9)
Fixed in ver.2.3.0.

No.29 Support for SkyTraq S1315F Receiver F/W ver.1.8.23-091106 (RTKNAVI, RTKCONV ver.2.2.2)

From the F/W ver. 1.8.23-091106 for S1315F, the polarity of raw carrier-phase measurement is inverted. For this F/W or the later version, please apply the patch rtklib_2.2.2_p3.zip after applying rtklib_2.2.2_p2.zip and rebuild AP. Executable binary APs (RTKNAVI, RTKCONV) on Windows with the patch rtklib_2.2.2.p1.zip, rtklib_2.2.2_p2.zip and rtklib_2.2.2_p3.zip can be downloaded as rtklib_2.2.2_bin_p1p3.zip. (2009/11/10)
The patch is included in ver.2.3.0.

No.28 Support for SkyTraq S1315F Receiver (RTKNAVI, RTKCONV ver.2.2.2)

To add the support for SkyTraq S1315F Receiver, apply the patch rtklib_2.2.2_p2.zip and rebuild APs. Select "SkyTraq" for the receiver format. Binary messages of ID 0xDD (221: RAW_MEAS), ID 0xE0 (224: SUBFRAME) and ID 0xDC (220: MEAS_TIME) are necessary for positioning. (2009/10/20)
You need F/W 010823 rev.091009 or later version for S1315F.

Executable binary APs (RTKNAVI, RTKCONV) on Windows with the patch rtklib_2.2.2_p1.zip and rtklib_2.2.2_p2.zip can be downloaded as rtklib_2.2.2_bin_p1p2.zip. (2009/10/24)

No.27 Support for Hemisphere Eclipse Receiver (RTKNAVI, RTKCONV ver.2.2.2)

To add the support for Hemisphere Eclipse Receiver, apply the patch rtklib_2.2.2_p1.zip and rebuild APs. Select "Crescent" for the receiver. With the patch, message bin 76 (dual-frequency raw data) can be used as well as message bin 96 (single-frequency raw data). Don't output both messages of bin 76 and bin 96 simultaneously.

No.26 Improper antenna correction when Antenna Type is blank (RTKNAVI, RTKPOST ver.2.2.2)

In case that "Antenna Type" in "Options"-"Postion" dialog is checked but "Antenna Type" field is set to blank, the positioning is unable due to improper antenna correction.

Due to the bug in rtkcmn.c. It will be fixed in the next version. Don't leave "Antenna Type" field blank if checked. (2009/10/09)
Fixed in ver.2.3.0.

No.25 Improper row height of string-grid with non-standard DPI font scale (RTKNAVI, Ntrip Source Table Browser etc ver.2.2.1-)

In case of setting the screen font scale bigger than standard 96 DPI, the row height of string-grids is too narrow to read the text.

Due to the bug to set the height of the string-grids. It will be fixed in the next version. Please set the screen font scale to standard value (96 DPI). (2009/09/23)
Fixed in ver.2.3.0.

No.21 Unable to fix integer ambiguity for RTK-GPS with u-blox LEA-5T (F/W ver.6.00) (RTKNAVI ver.2.2.1-)

Integer ambiguity for RTK-GPS is not fixed with u-blox LEA-5T (F/W ver.6.00).

The LEA-5T (F/W 6.00) carrier-phase observables contain large abnormal residuals over a few cm as peak-to-peak variation (Here is an example of phase residuals of PRN02 with LEA-5T F/W 6.00. By LEA-4T for comparison). The carrier-phase anomaly degrades the estimated float ambiguities and the integer ambiguities are hard to be fixed. It might be due to LEA-5T F/W 6.00 problem. The inquiry mail was sent to the u-blox support. The reply will be shown here. (2009/7/27)
The reply from u-blox states that the carrier-phase anomaly is due to the bug of LEA-5T F/W 6.00. (2009/8/4)
In F/W 6.02 released in December 2009 (Release Notes), the problem of the carrier-phase anomaly is solved. Currently user-upgradable F/W image for ver.6.02 is not provided by u-blox. To update the old F/W of receivers, please contact u-blox directly (www.u-blox.com). (2009/12/9)

No.19 Can not input receiver raw binary stream from serial device in Linux (CONVBIN ver.2.2.1-)

In Linux environment, receiver raw binary stream is not recognized from serial device and can not be converted to RINEX with CONVBIN.

In normal mode, Linux serial device can not handle binary data stream. Execute convbin after setting the serial input device to raw binary mode with the stty command as follows. (2009/7/2)

$ stty raw < /dev/ttyACM0
$ convbin -r ubx -f 1 -o ubx.obs -n ubx.nav -s ubx.sbs /dev/ttyACM0
