Garmin GPS 18 5Hz Sensor with Bare Wires

Details

The Garmin GPS 18 5Hz is an OEM GPS sensor for use in machine control, guidance and agricultural applications that require 5 Hz position and velocity reports from a small, highly accurate GPS receiver.

Use in Small Spaces

This 12-parallel-channel, WAAS-enabled GPS comes with an integrated magnetic base for easy mounting. The puck-like receiver is 2.4 inches in diameter and weighs just a few ounces, making it an ideal solution for applications where space is at a premium.

Get Precise Position Data

The GPS 18 5Hz stores configuration information in non-volatile memory so it starts up quickly each time you use it. It also has a real-time clock and raw measurement output data for sophisticated, high-precision dynamic applications. For extra precision, it offers 5 Hz Measurement Pulse Output with rising edges that align to precise 0.2 second increments of UTC time, as long as the receiver has reported a valid and accurate position within the past 4 seconds.

Package Includes

• GPS 18 5Hz with 5 meter cable (bare wire connection)

Interfaces

• Electrical Characteristics: TIA-232-F (RS-232) compatible asynchronous receiver. Default setting is 19200 baud.
• Protocols: NMEA 0183 Version 2.0 or NMEA 0183 Version 2.30
• Available NMEA 0183 output sentences include GPALM, GPGGA, GPGSA, GPGSV, GPRMC, GPVTG, GPGLL, PGRME, PGRMF, PGRMT, PGRMV, and PGRMB (Garmin proprietary sequences).
• Configuration and initialization is accomplished with NMEA 0183 input sequences. Allows initialization of information such as expected position, date, time, earth datum, and differential mode.
• Configurable for binary data output including GPS carrier phase data.

Measurement Pulse Output

• 5 Hz pulse synchronized with the time of fix. One of the five pulses will align with the UTC second boundary. The pulse width is programmable from 20 ms to 180 ms. The PGRMC sentence will indicate which pulse is at the top-of-the-second.
• 1 µs accuracy for all conditions in which the GPS 18-5Hz has reported a valid and accurate position fix for at least the previous 4 seconds.
