Første SiRFstarIV GPS-moduler lanceret

Vincotech lancerer de første GPS receivermoduler med SiRF starIV og SiRFaware teknologi (in english).

Vincotech, a leading supplier of GPS receiver and telematics hardware solutions, launches the first modules based on the latest SiRFstarIV technology. The A2100 GPS receiver module is built around the new GSD4e chip with sophisticated firmware.

The special SiRFaware technology allows the module to be in a state of readiness at all times thereby enabling rapid navigation for long periods.

SiRFaware will monitor and maintain precise time, internal frequencies and satellite orbit information (ephemeris) - all at an extremely low current draw down to 500 µA. Thus the A2100 will be able to respond to a position request within seconds. Continuously reporting a fix in Advanced Trickle Power mode can be achieved with a current draw of less than 6.5 mA.


Combining the outstanding tracking sensitivity of -163 dBm and an autonomous acquisition sensitivity of -148 dBm, the module is ideally suited for all GPS applications requiring low power consumption in harsh environmental conditions.

In addition, the new GSD4e chip on the module supports detection and removal of up to 8 in-band jammers and allows the use of satellite-based augmentation systems. SiRFInstantFix, an extended ephemeris solution, combined with SiRFawareTM help to further reduce power consumption.

The module itself is offered in a 3.3-V and a 1.8-V variant, both flash versions allowing firmware upgrades, with the 3.3-V version being compatible to the popular A1084-B. The A2100 is designed to support additional sensor interfaces as well as communication via UART, SPI, or I2C. Samples and evaluation boards are available in February, with series production scheduled to begin in March 2010.
