Performance specifications
Applicable receivers: BD940 | BD940-INS | BD990 | BD992 | BD992-INS | BX940 | BX992
NOTE – The Time to First Fix specifications are typical observed values. A cold start is when the receiver has no previous satellite (ephemerides/almanac) or position (approximate position or time) information. A warm start is when the ephemerides and last used position is known.
