Y1-03-0233 Rev. F 28This bypasses the normal, programmed, waiting time of 20 minutes forthe automatic update of GPS position data.If the new GPS position is acquired, the coordinates will be displayedafter the beacon has completed the Self-Test. If no valid GPS positiondata is available, the beacon will keep the previously stored GPS positiondata for up to 4 hours. In this case, call ACR Customer Service at +1(954) 981-3333 for instructions on how to reset the beacon with thedefault message.A new beacon is programmed with the GPS position data set to a default.If the beacon should be activated, this default GPS position dataindicates to the satellite system that the beacon has no valid GPSposition stored in memory. Once a functioning and compatible externalGPS receiver is properly connected to the beacon, the default data willbe replaced by valid GPS position data, as described in the previoussections.5. Internal GPS position systemThe GlobalFix™ iPRO is fitted with an internal GPS receiver that willdetermine the coordinates (latitude and longitude) of the beacon’sposition on the globe, to be transmitted to the Cospas-Sarsat emergencysystem.When the beacon is turned on, the internal GPS is immediately turned onand it attempts to acquire positional coordinates. GPS coordinates canbe acquired any time that the GPS is on, but only valid data is saved.Once the beacon acquires valid coordinates, the data is included as partof the next transmitted 406 MHz digital message.The internal GPS operates on a schedule during which the beacon is onfor a time, actively acquiring coordinates, and off for a time, in a restingstate. The schedule is designed to conserve battery but, at the sametime, assure that navigational coordinates are regularly updated.6. LED indication of GPS fixWhen the beacon is activated and valid coordinates are acquired, thedata is included in the digital message of the next 406 MHz transmission.The LED blinks green when GPS coordinates are sent.If a time period of 4 hours passes without the internal GPS receiver beingable to update the last good set of navigational coordinates, the messagetransmitted by the beacon will revert back to default data. At this point thegreen LED will stop blinking and the red LED will flash. The internal GPSwill continue to seek coordinates and when successful the green LED willflash. This new data will be transmitted in the next message burst andthe green LED will continue to flash.
