Microcontroller with remote functionality configuration. High fidelity Radiophone. Location unit "plug and play", without vehicle installation.

Product Description:

The GPS-P is a device integrated in a radiophone portable microphone SIRDEE TETRAPOL.

Versatile unit
The GPS-P devices offers two different functionalities:

Use as radiophone with P.T.T. (Push To Talk) fully compatible with TETRAPOL terminal
GPS location and transmission of the position data by the TETRAPOL network (SIRDEE in Spain and ACROPOL in France) of Interior Ministry, based on AVL Polling schema powered by Tetrapol .

The GPS-P device follows a strict ergonomics criteria that allows a comfortable way of using. The connection with the radio Terminal is made by a spiral cable that allows a high mobility level, when it’s extended, but it’s gathered perfectly when it is not in use.

TThe GPS-P device has a metallic subjection clamp which offers a great robustness and 360º orientation, this allows the device collocation at the user’s shoulder

Maximum functionality
The GPS receiver included has 16 channels, high sensitivity, (-158dBm when following and –148dBm when acquiring) and extra low power consumption The GPS antenna is integrated in the GPS-P device.It is a helicoidally antenna which offers a omnidirectional signal reception. This set, GPS receiver and omnidirectional antenna, offers the better warranty to obtain the pedestrians location in any situation, as much in open field as in city.

The GPS-P device uses a 8 bits microcontroller that includes all the necessary memory to work ( Flash memory for Firmware, RAM memory for the volatile data and EEPROM for configuration file). This architecture allows to reduce to the maximum the size of the equipment. In the other hand, this microcontroller uses an extra lower power consumption(<3mA), this feature allows to expand the useful life of battery.

The GPS-P device contemplates the different layers from communication protocols used by the High Disponibility SAIR platform from the Interior Ministry of Spain, or the LOXANE platform of FRANCE. Additionally it allows the customization of the operation parameters to work with external AVL platforms.
