GPS Almanac Download
GPS Almanac downloader acquires GPS Almanac data directly from the satellite and can be uploaded into your system on start-up.
Have you've ever wondered why your GPS receiver sometimes takes longer to become ready to navigate after it's turned on? Your receiver has to acquire its almanac data in addition to capturing GPS satellite signals. You may encounter a slow start if your GPS has been unused for days or weeks.
US Coastguard GPS almanac data source can be up to a week out of date. Queslett’s GPS Almanac software downloads this data direct from the satellite on system start-up so you’ll always have the latest most accurate satellite positioning data.
The GPS almanac is a set of data that every GPS satellite transmits, and it includes information about the state (health) of the entire GPS satellite constellation, and coarse data on every satellite's orbit. When a GPS receiver has current almanac data in memory, it can acquire satellite signals and determine initial position more quickly.
Queslett’s GPS Almanac software also includes GPS clock calibration data, and data to help correct for distortion caused by the ionosphere.
