Generally GPS in gps store a variety of uses, ranging from handheld, handheld GPS, Aviation, marine, and geology that have a high enough accuracy. In general, all GPS functions such as computers, because there is input, process and output, even some processors to use Intel as a brain / function counted.
When GPS was found, his acquiring (capture satellite signals) takes a long time, or a new GPS that has moved far away and had a very long unlit take up to tens of minutes, generally 10 s / d for 15 minutes of new products, while for which had been lit around the bias is pressed 2 to 3 minutes, depending on the type, and technique, usually given autolocate takes longer than the defined position, or in the recycle and turn off again. Sometimes by moving the position to achieve the optimum antenna position can accelerates the process. There are difficult if in the car using a glass films using a high UV protective.
Maintenance / Trouble Shooting
Why sometimes the GPS rather die myself: This might happens 2 possibilities, software or hardware; in software bugs or are there commands that do not match those planned, while the hardware typically save battery connector if the battery on a long period resulting in condensation or evaporation which can cause corrosion (Contact bad) or if the spring / by the less powerful battery to turn off the GPS when exposed to shocks, and if often happens the instant power ON & OFF will shortens the age of GPS.
WARNING: Do not forget to disconnect the battery when not in use in a long period of time.
Operational
After lighting the GPS other aspects of utilization depends on the user, from the operational GPS (for example in the shop gps) is best can be felt in aviation because there are other functions of the lateral vertical functions. Where the vertical functions are used between others to determine when to lower the altitude of the aircraft with the rate of decent is not painful ear 500ft/min example below.
Database / GPS Program
Consists of various types:
Baseline program / memory: This program was written as calculation software, the system was made permanent (non-user editable), except with special programs.
Extended Programs / memory: for extended programs like the hard drive is usually partitioned in which the original partition only ROM (Read Only Memory) is on another partition RW (Read Write), for GarminII / GPS12 / Longer externally no big function, so only allocated for Waypoint & Track course, was for a greater like GPS SPIII / 295 there is an external program and external memory for the map.
WARNING: Do not forget to backup your data, because the internal battery is weak RAM (memory) can be lost.
