As explained in the GPS Reset window, you may reduce

the time to first fix by running the GPS Initialization utility

(see Initializing GPS on page 12). Until a new almanac

file is received from the GPS constellation, MobileMapper

CE uses a non-erasable almanac file stored in its memory

to start the satellite acquisition process.

Mission Planning

The Mission Planning utility enables you to view the visibility

and availability of the constellation of satellites and determine

the dilution of precision (DOP) for any location on the Earth.

It allows you to plan the best time of the day for data collec-

tion and maximize productivity.

To be able to determine the configuration of satellites, an al-

manac file is used in Mission Planning. This file is generated

and loaded automatically when you get the first GPS fix.

- Tap on , then Programs>GPS Utilities>Mission Planning.

The Mission Planning window appears (see opposite) with

the sky plot and PDOP (satellite geometry) graphs. Top left

of the screen is the name of the almanac file used to make

the satellite prediction (alm<year (last two digits)><day in

year (1-365)>).

- Instructions for proper use of Mission Planning are sum-

marized in the table below.
