GPS16X-HVS-PW

GPS16X-HVS-PW GPS16X-HVS Garmin GPS High-Sensitivity Receiver w/Integrated Antenna (-30 to +80C), 4.5m (15ft) Cable -PW w/Pre-Wire Connector

Note: The prewired version of the GPS16X-HVS is now available as an option on the GPS16X-HVS page. 

The GPS16X-HVS-PW is a global positioning system (GPS) receiver that provides position, velocity, and timing information. Campbell Scientific configures the GPS16X-HVS-PW and modifies its cable so that the receiver can more easily interface with our data loggers. This receiver's cable is fitted with a connector for attachment to our prewired enclosures.

Position and Time
Precision time synchronization

The GPS16X-HVS-PW consists of a receiver and an integrated antenna. It receives signals from orbiting Global Positioning System (GPS) satellites, and then uses the signals to calculate position and velocity. The GPS16X-HVS-PW also provides a highly accurate one-pulse-per-second (PPS) output for precise timing measurements.

The GPS16X-HVS-PW is manufactured by Garmin International. Campbell Scientific configures the receiver and modifies its cable. The modified cable terminates in a connector compatible with our PWENC prewired enclosures, that then attaches directly to the control ports of a CR800, CR850, CR1000, or CR3000 datalogger.

The default settings are typically used. Changing the default settings or options requires additional hardware to connect to a PC running GPS16 software. (See the Ordering Info on the web page.) The software can be downloaded, at no charge, from the Garmin website (www.garmin.com). 

By default, the instruction expects the GPS unit to be set up at 38400 baud, outputting the GPRMC and GPGGA sentences once per second. The data logger expects the start of the second to coincide with the rising edge of the PPS signal. If there is no PPS signal or if the required sentences come out at less than once per second the data logger will not update its clock. GPS units with lower baud rates can be used with the GPS instruction but the baud rate has to be set for the relevant Com port it is to be connected to either in the data logger settings or by including a SetStatus command after the BeginProg instruction in the program (e.g., SetStatus("BaudrateCOM4",19200)). Baud rates below 2400 bps will not work as the GPS unit will not be transmit the two GPS sentences once per second reliably. Similar problems can be encountered even at higher baud rates if too many optional GPS strings are selected to be output.
