The 406 MHz signal is detected by multiple satellites and from that
information the location of the beacon can be calculated. This data
alone is sufficient for SAR to find persons or ships in distress in a
reasonable timeframe. However, as a further enhancement, some
beacons have a GPS engine onboard. This feature allows the beacon to
acquire current location coordinates from an internal GPS receiver. The
purpose of this feature is to send an even more precise location of the
beacon to the satellites, i.e., latitude and longitude data. This helps SAR
to reach the location even faster.
2. Internal GPS position system
The PLB-350C is fitted with an internal GPS receiver that will download
the coordinates (latitude and longitude) of the beacon’s position on the
globe, to be transmitted to the Cospas-Sarsat emergency system.
When the beacon is activated, the internal GPS immediately attempts to
acquire positional coordinates. GPS coordinates can be 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 part of the next
transmitted 406 MHz digital message.
The internal GPS operates on a schedule during a beacon activation.
The GPS is on for a time, actively acquiring coordinates, and off for 20
minutes, in a standby state. The schedule is designed to conserve
battery but, at the same time, assure that navigational coordinates are
regularly updated.
3. Optional beacon management and testing services
Additional features and through satellite testing services are available for
this beacon when you subscribe to the SafeLife System. When you sign up
for this optional service you can test your beacon and have confirmation
messages sent to your cell phone or email. Expanded services also will
include friends and family contact information for check in messaging. Visit
406Link.com for complete details. (This service is not required for your
beacon to function as a Personal Locator Beacon.)
