Fastrax has introduced the IT430, the first GPS receiver in the company’s new IT400 series of GPS modules.
As one of the first commercially available modules based on CSR’s latest generation SiRFstarIV architecture and SiRFAware technology, the module offers a range of features designed to speed the inclusion of location-aware features in battery operated consumer devices. The complete module is packed into a tiny casing for easy fitting into various battery operated appliances.
Traditionally, location aware features such as automatic geotagging of digital photos have suffered from longish times for location information to show. The situation is especially challenging in urban environments, where the limited visibility of GPS satellites and interference caused by indirect signals reflected from buildings make it more difficult to reliably determine a position.
Convenient use of location aware applications in digital cameras, mobile phones and other battery driven devices usually require keeping the GPS active at all times, leading to increased battery consumption. With its new innovative SiRFAware mode, Fastrax IT430 autonomously activates periodically to maintain awareness of its location at all times and consumes only 500 μA average current. As a result, updated location information is available almost immediately when activated, without compromising battery life.
The module integrates TCXO, RTC and SAW filter into its 9,6 x 9,6 x 1,85 mm form factor. It supports both active and passive antennas with an input for externally generated antenna bias supply. The IT430 is especially well suited to battery operated devices using 1,8 V internal power regulation. The low-powered GPS module consumes only 56 mW at 1,8 V in full operation mode and only 20 μA current in hibernate state.
