Motorola Oncore GPS Receiver. Motorola Oncore GPS receiver. Synopsis. Address: 1. Reference ID: GPSDriver ID: ONCORESerial Port: /dev/oncore. PPS Port: /dev/oncore. PPS. The VP is no longer available new, and the UT, GT, and SL are at end- of- life. The Motorola evaluation kit can be recommended. It interfaces to a PC straightaway, using the serial (DCD) or parallel port for PPS input and packs the receiver in a nice and sturdy box. Less expensive interface kits are available from TAPR and Synergy. The driver requires a standard PPS interface for the pulse- per- second output from the receiver. The serial data stream alone does not provide precision time stamps (0- 5. PPS output is precise down to 5. VP/UT models and 2. View and Download Motorola Oncore GT quick start manual online.

M1. 2 Timing. If you do not have the PPS signal available, then you should probably be using the NMEA driver rather than the Oncore driver. The driver will use the . When first starting to use the driver you should definitely review the information written to the clockstats file to verify that the driver is running correctly. See the Oncore- SHMEM manual page for information on how to use this option. For either debugging or using the SHMEM option, an Oncore Reference Manual for the specific receiver in use will be required. Fudge Factorstime. WD6CMU's Super-Accurate Clock. A long, long time ago, in a far-away land known as Benton. The receiver used is the Motorola Oncore UT+ module purchased from Synergy Systems. Motorola Oncore GPS receiver. UT, UT+, GT, GT+, SL, M12, M12+T), as long as they support the Motorola Binary Protocol. MOTOROLA ONCORE MANUAL - Free Download MOTOROLA ONCORE MANUAL MOTOROLA ONCORE MANUAL instructions guide, service manual guide and maintenance manual guide on your products. Before by using this manual, service or maintenance. Acquire a Motorola OnCore M12+ OEM GPS module. I selected the Motorola for several reasons. The eBay seller listed below had them for $55. Specifies the time offset calibration factor, in seconds and fraction, with default 0. The offset shifts the PPS signal to avoid interrupt pileups `on' the second, and adjust the timestamp accordingly. See the driver source for information on this file. The default with no file is: no delay, no offset, and a site survey is done to get the location of the gps receiver. The edge of the PPS signal that is `on- time' can be set with either flag. Flag. 3 (or the word HARDPPS in the driver specific configuration file) will cause the PPS signal to control the kernel PLL. Performance. Really good. With the VP/UT+, the generated PPS pulse is referenced to UTC(GPS) with better than 5. The limiting factor will be the timebase of the computer and the precision with which you can timestamp the rising flank of the PPS signal. Using Free. BSD, a FPGA based Timecounter/PPS interface, and an ovenized quartz oscillator, that performance has been reproduced. For more details on this aspect: Sub- Microsecond timekeeping under Free.
