Technology

GPS Satellites:
21 ft. (6.4 m) location accuracy

LEO Satellites:
1610-1620 MHz L-band frequency

Satellite Speed:
17,000 MPH
114 min. to circle the earth

Distance:
876 miles above Earth
Altitude (twenty times closer than fixed satellites)

Requires less power
Less power usage allows more frequent updates
Less power usage allows other value-added uses

Visibility:
1 to 4 at any one time
More satellites for SOS detection than anyone
More satellites means signal can be detected sooner
Angle of detection:
Constantly changing, helps in dense coverage

Beam Coverage:
Overlaps, increased detection probability

Movement:
Constantly, 8 planes 52 degree inclination

Communication:
If no GPS fix, SPOT sends distress signal without GPS position to emergency response center
Previous Check In or Track Mode data provides fast and close proximity
