Lightweight GPS module expands animal research
A technology partnership will soon make it possible for scientists to study the behaviour of endangered species once thought too tiny to be tracked by GPS.
The LEA-4H also consumes 40% less power than its predecessor, features advanced power management options, excellent navigation performance, high sensitivity and an outstanding performance-to-cost ratio.
SuperSense software is able to detect the weakest signals and to provide uninterrupted GPS reception and accurate position calculations in buildings, hidden places in motor vehicles and other locations with obstructed views to the sky.
This state-of-the-art technology, which provides acquisition and reacquisition sensitivity of -148dBm, cold start sensitivity of -142dBm and unmatched tracking sensitivity of -158dBm, does so without compromising on power consumption, which stays low at even the weakest signals.

Tracking technology makes sense of weak GPS
Atmel and u-blox have codeveloped a new GPS weak-signal tracking technology, called SuperSense, supporting Atmel's Antaris GPS chipsets and GPS modules from u-blox.
Firmware upgrades GPS chipset performance
GPS module maker u-blox has released the final SuperSense firmware for its TIM-LH GPS receiver modules and Antaris GPS chipsets.
Thanks to advances in hardware and software achieved with the 16-channel Antaris 4 receiver technology, Antaris 4 chipsets, a joint development of Atmel and u-blox, allow for 40% smaller modules, USB connectivity, full support of WAAS and EGNOS satellites and unparalleled low power consumption.
This makes the LEA-4H module ideally suited for battery-operated products such as PDAs, smart phones and other portable devices where size, sensitivity and power consumption levels are critical.
"The LEA-4H is particularly well suited for consumer mobile and telecommunication products thanks to a significant reduction in power needs and in module sizes".
"Other features that benefit handhelds are USB connectivity and SuperSense indoor GPS capabilities", said Georg zur Bonsen, Product Manager.
"Antaris 4 modules are particularly well suited for consumer mobile and telecommunication products thanks to a significant reduction in power consumption needs and in module sizes".
"Other features that will benefit handhelds are the USB connectivity of the LEA-4H or the SuperSense indoor GPS capabilities of both the LEA-4H and the TIM-4H modules", said Bonsen.
Antaris 4 receivers are also endowed with Assisted GPS (A-GPS) functionality, which provides instant positioning on request.
This function drastically reduces time to first fix (TTFF) to as low as four seconds, as well as enabling signal acquisition in difficult environments.
One use of A-GPS is the provision of emergency call and instant location services.
A-GPS is also commonly used to access immediate location information in difficult signal environments.
