Garmin GPS 17HVS RS232 Sensor

The new Garmin GPS 17HVS is designed primarily for use in marine applications and can be flush mounted in addition to pole mounted. It delivers exceptional accuracy while standing up to the harshest environment (meets IEC 60529 IPX7 standards). The 12-channel receiver allows for continuous tracking of all visible satellites - and it's WAAS capable, which means it can provide position accuracy of less than three meters (on average). This incredible accuracy is possible without the use of an external DGPS beacon receiver. The GPS 17HVS also offers excellent EMI/RFI performance for easy integration into systems that will be operated near mobile computing devices and wireless communications equipment.

This GPS receiver produces asynchronous serial data at true RS-232 levels in the industry-standard NMEA 0183 data format. This makes it ideal for interfacing to devices (such as laptops and chartplotters) that expect to hear NMEA 0183 data from a serial com port. The GPS 17HVS also is capable of producing a TTL-level Pulse-Per-Second (PPS) signal whose rising edge is aligned to the UTC second boundary within 1 uS for all conditions in which the GPS receiver has produced a valid and accurate position for at least the previous four-second interval.
