16-Channel Reception System It can receive signals from up to 15 GPS satellites at the same time, using the all-in-view technique to calculate your position extremely precisely from all receiver satellites. The system also had one dedicated channel for fast satellite searches. Compact, Light, and Power-Saving A new downconverter LSI and digital ASIC trim the size roughly 70%, halve the weight, and slash power consumption 55%. Fast TTFF The dedicated search channel shortens TTFF, reducing the time taken for positioning from cold starts by around 80%. Antenna Power Input Inputting in the antenna power input terminal for the voltage used by the antenna allows the use of 3- and 5-volt antennas. To use 3-volt antennas, you can externally link the antenna power input terminal to the main power input terminal. Incorporating Antenna Diagnostic Circuit Incorporates a diagnostic circuit to monitor the current supplied to the antenna, letting you detect when the antenna circuit shorts or is open.
