QUICK START GUIDE

MOTOROLA Oncore™ GT

GPS Module for Embedded OEM

A rugged and reliable eight-channel receiver, the Oncore™ GT provides position and velocity

data anywhere on Earth, at any time of day, in any weather. It also provides accurate time. A

one-pulse-per-second signal output is synchronized to UTC within a nominal accuracy of five

hundred nanoseconds—ideal for multi-site synchronization and time-distribution applications.

Features

• 8-channel parallel receiver, 8 simultaneous satellite vehicles, L1 1575.42 MHz

• Code plus carrier tracking (carrier-aided tracking)

• Velocity: 1000 knots (515 m/s); > 1000 knots at altitudes < 60,000 ft.

• Position filtering

• Antenna current sense circuit

• Operates from +5 Vdc regulated power

• TTL interface to host equipment

• 3-dimensional positioning within 25 meters, SEP (without Selective Availability [SA])

• Latitude, longitude, height, velocity, heading, time, and satellite status information output either

continuously (once per second) or polled

• Differential GPS with Motorola binary corrections

• RTCM SC-104 differential GPS correction input on second comm port

• Motorola binary protocol at 9600 baud

• NMEA 0183 output at 4800 baud: GGA, GLL, GSA, GSV, RMC, VTG, ZDA sentences

• Velocity filtering

• 1PPS output (+/- 500 ns accuracy)

Time To First Fix (TTFF)

• < 15 s typical TTFF-hot (with current almanac, position, time and ephemeris)

• < 45 s typical TTFF-warm (with current almanac, position and time)

• < 90 s typical TTFF-cold
