The new SE867-AGPS is the smallest module in Telit portfolio, and the first GPS standalone module featuring state-of-the-art GPS characteristics, with the high quality and great support that usually accompany Telit products.
SE867 -AGPS is an assisted GPS module designed for the M2M market, offering extremely fast TTFF, low cost and short integration time.
Why Assisted GPS:
Assisted GPS, also known as A -GPS or AGPS, enhances the performance of standard GPS in devices connected to the cellular network. A -GPS improves the location performance of mobile devices in two ways:
-By helping obtain a faster "time to first fix" (TTFF). A -GPS acquires and stores information about the location of satellites via the cellular network so the information does not need to be downloaded via satellite.
-By helping position a mobile device when GPS signals are weak or not available. GPS satellite signals may be impeded by tall buildings, and do not penetrate building interiors well. A -GPS uses proximity to cellular towers to calculate position when GPS signals are not available.
The SE867 -GPS includes an internal processor and an 8Mb flash memory with 44 channel operation and less than 35 sec time to first fix (TTFF) making the SE867 -GPS module one of the leading receivers in the market place.
Designing in the SE867 -GPS is very straight forward, a BGA device that has been designed so that the module can be easily placed even in a simple 2 layer PCB and the integration with our extensive range GPRS devices is very straight forward and simple.
The SE867 -GPS is the perfect product for a varied range of M2M applications such as vehicle tracking, asset tracking, data collection or really any project where having access to positional data and status information of a physical asset is a key benefit or mandatory requirement
Sequoia's technical team can help with all aspects of a design based on the SE867 -GPS, reference schematics are available together with a development kit.
