SiRFstarIV Modules
09 February 2010
The focus is on fast fix and high availability with SiRFaware on A2100 GPS modules.
Supplier of GPS receiver and telematics hardware solutions, Vincotech, is launching its first modules based on the latest SiRFstarIV technology.
The A2100 GPS receiver module is built around the GSD4e chip with sophisticated firmware. The special SiRFaware technology allows the module to be in a state of readiness at all times, enabling rapid navigation for long periods.
SiRFaware technology is one of the highlights of the new A2100 module. It will monitor and maintain precise time, internal frequencies and satellite orbit information (ephemeris) – all at an extremely low current draw down to 500µA. 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 6.5mA. Combining the outstanding tracking sensitivity of -163dBm 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 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 SiRFaware help to further reduce power consumption. The module is offered in a 3.3V and a 1.8V variant, both flash versions, allowing firmware upgrades, with the 3.3V version being compatible to the 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 now, with series production scheduled to begin in March 2010.
For Hans Wiedemann, Manager Product Marketing at Vincotech, the A2100 module is clearly in line with the current market trend: “The SiRFstarIV technology of CSR answers the most urgent questions of all GPS applications; high availability combined with lowest power consumption. We are very proud to be able to offer our modules to the market at this early stage – thanks to the great co-operation with CSR.”
