Help: ICE_KEYS_GPS

gets the time and position from an ICE-GPS IO Module

Returns an array of 6 doubles as (time,lat,lon,alt,status,nos) where time is 
in SecondsOfYear, lat and lon are in degrees, and altitude is in meters.
Nos is the number of satellites in view, and status is as follows:

  Status:
  0 - startup, wait for N satellites in view, flywheel at initial VCO settings
  1 - measure freq at initial VCO for 16 sec
  2 - measure freq at initial VCO + 2*dVCO for 16 sec
  3 - measure freq at initial VCO for 64 sec
  4 - measure freq at initial VCO + 2*dVCO for 64 sec (calculate dFreq/dVCO)
  5 - normal operation with phase tracking correction 
  6 - normal operation with phase tracking correction averaged at least one minute
