GT-750F

54 Channels Excellent Performance Bluetooth® GPS Receiver

SERUTAEF TCUDORP NOITPIRCSED LARENEG

The GT-750F is a single board of Bluetooth GPS receiver for customers who require easy system integration and minimal development risk. The GT-750F is optimized for excellent performance and low cost. Its 54 parallel channels and Skytraq low power chipset search bins provide short start-up time and fast signal acquisition. Having fast time-to-first-fix and high sensitivity, the GT-750F offers good navigation performance even in urban canyons. Satellite-based augmentation systems, such as WAAS and EGNOS, are supported to yield improved accuracy. Besides it also supports A-GPS function and fixed in the short time. The on board patch antenna provides good signal reception. It provides fast satellite signal acquisition and short startup time. Acquisition sensitivity of –155dBm and tracking sensitivity of –159dBm offers good navigation performance even in urban canyons having limited sky view. Class 2 Bluetooth offers up to 10 meters of wireless operation with Bluetooth-enabled devices such as PDA, laptop PC or Smart mobile phone.

Assisted GPS With Assisted GPS technology, GPS Data (ephemeris data) will be downloaded from an A-GPS Server through internet and transferred to the GT-750F GPS via Bluetooth. This will greatly reduce the TTFF since the positions of the satellites are known. The downloaded GPS data will expire in few 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.
