65 Channels USB GPS Receiver / Support AGPS

For Desktop, Laptop, Ultra Mobile PC,Mobile Internet Device

 65 Channels USB GPS Receiver Dongle is a single board of GPS USB dongle receiver for customers who require easy system integration and minimal development risk. Its 65 parallel channels and Venus 6 search bins provide short start-up time and fast signal acquisition. Having fast time-to-first-fix and high sensitivity, it offers good navigation performance even in urban canyons. This USB GPS Dongle is capable of keeping up to 256K recordsor positions, including longitude, latitude, speed, UTC,and tag data. The location histories can be exported to mapping software such as Google Earth or TrackMaker. 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 onboard patch antenna provides good signal reception. It provides fast satellite signal acquisition and short startup time. Acquisition sensitivity of –155dBm and tracking sensitivity of –160dBm offers good navigation performance even in urban canyons having limited sky view. USB interface are provided on the interface connector. Supply voltage of 3.8V~8.0V is supported.

Assisted GPS:
With Assisted GPS technology, GPS Data (ephemeris data) will be downloaded from an A-GPS Server through internet and transferred to the GPS via USB. 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.
