EMSIS – User's and Installation Manual
V active antenna with SMA male connector can be used.
The AHRS unit, which is hosted by the EMSIS PFD unit, has an internal super capacitor which provides
power for the GPS for about 14 days after the last flight. It enables so called hot-start of the GPS module.
A hot-start means that GPS constellation almanac is kept in the GPS module memory after the EMSIS unit
was powered OFF.
Note: On a first start up, on a cold-start or when EMSIS PFD is moved for a significant distance without
receiving GPS signal (shipping across the Globe), GPS receiver needs to download almanac from the
constellation. This requires a good GPS signal and may take a few minutes.
