high sensitivity SirF Star 3 iii GPS module with patch antenna for GPS tracking system
Product Description
The GPM220 is based on SirF Star 3 chip set. It possess 20-channel all-in-view GPS tracking that reaches extremely high TTFFs at low signal levels and high sensitivity for indoor fixes. Equipped with vertically installed 18x18x4mm patch antenna eliminate the transmission loss of external antenna and hence increase the receiving sensitivity.
The host Interfaces include is the UART port, which used for GPS data and receiver control. The transmit and receive side of UART port contains a 16-byte deep FIFO with selectable bit rates ranging from 1.2 to 115.2 K baud. The default is 57.6K bauds.
In order to keep the warm start data while power transient or battery exchanging to the module, it has been equipped with a super capacitor which can support up to 30 minutes operations of RTC and the memory that maintain the almanac data of the GPS satellites.
Applications
Handheld GPS tracking device.
Transportation tacking system.
Maritime GPS tracking system.
Product Benefits
On board patch antenna provides better antenna gain
Vertically installed patch antenna
Low tracking power consumptions of only 50mW
Short term back up power for RTC and almanac data of GPS satellites
