GP-2 – Mobile Automotive GNSS Multisystem Receiver (SKU#191)
(photo in preparation)
The GP-2 mobile GNSS receiver is an automotive version of our GP-1 receiver, and is designed to receive the signals from two (in Europe three) geolocation systems – GPS / Glonass (/ Galileo) and it can be connected to LunaBat DFR-1 ultrasound bat detector or to our future devices. Receiving signals from more than one geolocation system significantly increases the number of satellites seen by the device, which can be useful in places with poor sky visibility or poor weather conditions. The continuity of the geolocation is improved, and to a certain extent accelerated the speed and increased accuracy of obtaining the geolocation.
The GP-2 receiver is designed to be connected with our LunaBat DFR-1 detector via the expansion slot. It has a magnetic base for placement on a large metal surface (such as a metal roof of a car, home, etc.). Due to the large internal surface of the active patch antenna, it can also operate without such a surface (so called „ground plane”). The receiver is equipped with a 1.5m cable with 8-pin industrial grade connector made by german Binder company.
It works with two (three in Europe) geolocation systems to keep your location in more severe conditions than if you were using only one system. When 2D or 3D fix is achieved, it is indicated by a blue blinkin’ LED located above the LCD screen on the detector. The receiver (when plugged in the expansion slot of the detector) stores ephemeris and almanac even after the detector is turned off, and when detector is re-enabled – achieving 2D or 3D fix is much faster than at first fix (this is called: Hot Start mode, when under 2 hours and Warm Start mode for more than 2 hours after turning off the detector).
Alternatively the GP-2 receiver can be also connected (via optional custom converter cable) to other compatible equipment*. GP-2 receiver also have a built-in independent MTK Locus logger (used in firmware versions prior to v.7.xx) which can be set to logging the route of the transect every 15 seconds** in the internal flash memory of the receiver. Once its contents is dumped (copied, moved) to eg. a memory card, the dump file could be converted to eg. Google KML or other format using the GPS Babel converter. In the LunaBat DFR-1 detectors since the firmware v.7.xx a Google KML file can be generated directly on the memory card based on the .txt logs written along with the WAV files, so the Locus logger function (however still fully operational) is not needed anymore and temporarily excluded from menu of the current LunaBat DFR-1 detectors.
_____________________________________________
* – compatible equipment has to be capable of receiving NMEA or MTK sentences with 9600bps base baud rate (it is default rate of the receiver module, which can be changed in the connected device via NMEA or MTK protocol). Also the supply voltage for receiver must be within 3.0-3.6V range.
** – default rate, it can be changed via MTK protocol
There is also GP-1 – miniature mobile version of this receiver – more info HERE.
