Solutions is offering a distinct product portfolio to address a wide area of applications. These range from traditional
telematics solutions to latest highly integrated consumer devices, all of them having their special requirements
towards a GPS module. Based on SiRFstarIII and now also SiRFstarIV chip sets,Maestro Wireless Solutions GPS
module solutions address different specific needs and combine high performance, low power consumption,
and simplified integration effort. Our modules comply with the RoHS standard and are 100% electrically
and functionally tested prior to packaging, thereby assuring the guarantee of the highest quality products.
PERFORMANCE
COMMUNICATION
1) The receiver has estimates of time/date/position and valid almanac and ephemeris data.
2) The receiver has estimates of time/date/position and almanac
3) The receiver has no estimate of time/date/position, and no recent almanac
4) An external current limiter is suggested to avoid damage in fault conditions
