New Versions of iSuite 3 GPS SDK and iTrax03 Firmware

Fastrax Ltd. (Finland) has announced the latest versions of the Fastrax iSuite 3 SDK and iTrax03 GPS receiver firmware with numerous new features and updates that significantly improve GPS reception in difficult conditions such as urban canyon environments.

The Fastrax iSuite 3 SDK can be used to rapidly modify the features and functionality of a GPS receiver, allowing receiver performance and power management to be tailored for any usage scenario. By utilising the spare CPU and memory resources of the GPS receiver, the Fastrax iSuite 3 SDK can significantly reduce the bill of materials and non-recurring expenses of GPS products.

The iSuite 3 SDK is used to develop customer-specific applications to be executed on Fastrax iTrax03 OEM GPS receivers. These applications can utilise the on-chip memory and file system for data and software code storage, and access the various I/O lines on the iTrax03.
