Trimble Navigation has introduced new firmware that adds Wide Area Augmentation System (WAAS) and European Geostationary Navigation Overlay Service (EGNOS) capability to its ultrathin Copernicus GPS receiver. The firmware allows users to take advantage of satellite-based augmentation systems for improved positioning accuracy.

Ultrasensitive GPS
The Copernicus GPS receiver is a complete 12-channel thumbnail-sized, surface-mount, low-power GPS unit for mobile devices, which is housed in a 19-by-19-by-2.5mm shielded module. The ultrasensitive Copernicus GPS receiver can acquire satellite signals and generate position fixes with high accuracy in extremely challenging environments and under poor signal conditions, according to the company. The receiver consumes typically 93.9mW (31.3mA) at full power with continuous tracking.

The Copernicus GPS module is a complete drop-in, ready-to-go receiver that provides position, velocity and time data. The receiver features the new Trimble TrimCore software technology that provides fast startup times and high performance in foliage and urban canyon environments. It's compatible with active or passive antennas.

With advancements in performance, sensitivity and startup times, the Copernicus GPS module enables system integrators to easily add GPS capability to a mobile device with minimal impact on its size or battery life at a very economical price, said Trimble. It is suitable for adding GPS to Bluetooth appliances, sport accessories, personal navigators or cameras, computer and communication peripherals as well as vehicle tracking, navigation and security products.

The single-sided receiver is packaged in tape and reel for pick and place manufacturing processes. It features a 28 reflow-solderable edge castellation interface so the module can be incorporated in a product design without costly I/O and RF connectors, said the company. The GPS receiver is RoHS-compliant.

Three protocols
The Copernicus GPS module is available in three protocols. Trimble's TSIP protocol offers complete control over receiver operation and provides detailed satellite information. The TAIP protocol is an easy-to-use ASCII protocol designed specifically for track and trace applications. The bi-directional NMEA 0183 v3.0 protocol offers industry-standard data messages and a command set for easy interface to mapping software.

The Copernicus Starter Kit provides everything a designer needs to begin adding GPS capability into their application. The kit includes the reference interface board, which provides a visual layout of the Copernicus module on a PCB including the RF signal trace and RF connector, as well as the I/O and power connections of the 28 signal pins. The kit also includes a power converter, power adapter, GPS antennas and software.

The Copernicus GPS receiver with WAAS/EGNOS firmware is expected to be available Q3 2007 through Trimble's distribution network.
