  • Page 10 1.4.1 Application Considerations 1) Interruptions in GPS RF signals can increase the Time To First Fix (TTFF). Antenna location with continuous clear line-of-sight visibility to all directions in the sky yields the best TTFF. 2) GPS signal reception quality can be determined by monitoring the signal to noise ratio fields in the $GPGSV sentence.

    satellite orbital data to achieve maximum acquisition performance. If significant inaccuracy exists in the initial data, or if the orbital data is obsolete, it may take from 5 to 15 minutes to achieve a navigation solution. The GPS 30/ 30 SL AutoLocate feature is capable of automatically determining a navigation solution without intervention from the host system.

  • Page 14 1) If the GPS 30/30 SL is not operated for a period of six (6) months or more, the unit will “search the sky” in order to collect satellite orbital information. This process is fully automatic but the host system should allow the GPS 30/30 SL to remain on for at least 12.5 minutes after the first satellite is acquired to complete collecting almanac data (see Section 4 for more...

    19087, Washington, D.C., 20036, U.S.A.). The GPS 30/30 SL interface protocol, in addition to transmitting navigation information as defined by NMEA 0183, transmits additional information using the convention of GARMIN proprietary sentences. The following sections describe the data format of each sentence transmitted and received by the GPS 30/30 SL.
