1 Introduction
Maestro’s GPS antenna receiver module A2035-H is a highly integrated GPS an-
tenna receiver module based on the technology of the GPS receiver module
A2100-A and a ceramic GPS patch antenna. The module is capable of receiving
signals from up to 48 GPS satellites and transferring them into position and timing
information that can be read over a serial port. Small size and high-end GPS func-
tionality are combined at low power consumption.
NOTE
: Care must be taken to implement an orderly shut-down sequence along with
supplying power for a certain period of time after initiating the shut-down sequence.
Abrupt removal or drop of power while the module is running has risks ranging from
minor impact on TTFF to fatal, permanent corruption of flash memory code area
(Please refer to
“Power ONOFF Sequences and Power-On-Reset (POR) on
A2100-AB
Application Notes”)!
