WondeX has released two new Bluetooth GPS receivers based on 44 channels Skytraq chipset with AGPS function and motion sensor for smart power management. BT-100Y has user replaceable battery and 17 hours of battery life while BT-760Y has built-in battery and 44 hours of battery life.
With Assisted GPS technology, GPS Data (ephemeris data) will be downloaded from an A-GPS Server through internet and transferred to the BT-760Y GPS via Bluetooth. This will greatly reduce the TTFF since the positions of the satellites are known. The downloaded GPS data will expire in 7 days if the GPS is not being used. If GPS receiver is being used on daily basis, GPS data will also be downloaded from satellites.
