Technical Description
The GPS16X-HVS consists of a receiver and an integrated antenna. This device receives signals from orbiting Geographic Positioning System (GPS) satellites then uses the signals to calculate position and velocity. The GPS16XHVS can also provide a highly accurate one-pulse-persecond (PPS) output for precise timing measurements.
The GPS16X-HVS receiver is manufactured by Garmin International. Campbell Scientific configures the receiver and modifies its cable. The modified cable terminates in pigtails that attach directly to the control ports of a CR6, CR800, CR850, CR1000 or CR3000 datalogger. In these dataloggers the logger clock is set and GPS position data read with a single instruction.
Default settings are typically used. The default settings and options are changed using GPS16 software, which is available, at no charge, from the Garmin website (www.
garmin.com). Additional hardware is required to connect the GPS16X-HVS to the PC running the GPS16 software (see Ordering Information for more information).

Benefits and Features
Supports real-time WAAS, EGNOS or RTMC corrections for accuracy of 3 to 5 m
Attaches directly to a CR6, regardless of functionality Connects directly to a CR800, CR850, CR1000, or CR3000 datalogger when PPP time-synchronizing functionality is not
used
Processes data from up to 12 satellites depending on the number of satellites viewable above the horizon
Allows the datalogger clock to be set to the highly accurate GPS time
Configured by Campbell Scientific to output RMC and GGA data strings at 38400 bps
Extremely accurate timing pulse (PPS) can be used to synchronize time between the datalogger and other instruments
