FAQS

This option is available in Navigation software version 5.5! First, set a destination. Then, go to Route from main menu for Detour option. Tapping on Detour will show a list of roads that you will be taken from start point to destination. Tap the roads that you want to avoid, and tap Route when done. The navigator will generate a new route that avoids those roads.

POI - NEAR ADDRESS is for users to search for POI near an address stated by the user, while POI - NEAR DESTINATION is for users to search for POI nearby your selected destination.

Global Positioning System or GPS is a space-based radio-navigation system consisting of a constellation of minimum 24 satellites orbiting the earth. It is operated by United States, Department of Defense (DOD). It provides users with accurate information on their position, velocity and time in all weather conditions anywhere in the world.

Prior to May 2, 2000, GPS access by civilian receivers were only able to enjoy an accuracy level of not better than 50 meters due to the so called selective availability (SA), which is inclusion of random timing error in the GPS signals put in by the US military as a security measure. However, this error was turned off on May 2, 2000 5.05 am (MEZ) because of shortage of military grade GPS receiver and the US department of defense had to purchase civilian grade to make up the numbers. This ensures the civilian grade GPS receiver is accurate to within 20m.

However, there are also instances where signal is very weak or disrupted, and then you might get even less accurate positioning.

To pinpoint your location, you need to get signals from at least 4 satellites. In order to get the signals, the navigator must not be in a building, underground car park or in a tunnel. This is because in order to use a GPS device, it must have direct access to sky.

If your device is unable to capture satellite signals, check the following:

• is your car windscreen heavily tinted? (tinted beyond JPJ regulation)
• is your car's location being hindered by tall buildings or trees?

There are a lot of reasons why a GPS signal will be less accurate or dropped. The common term for this situation is called GPS errors. There are many types of errors, the errors related to signals dropping in high rise building areas or under flyovers is called the multipath effect. This is caused by signal reflecting off objects such as concrete buildings, mirrors, metals and other reflective materials. Because the signals are reflected and not travelling in a straight line, it takes longer to reach the receiver, hence causing a delay which will be interpreted as a different location by the GPS receiver. In serious cases, signal will be intermittently dropped.

While you may not be able to receive signals while driving in the tunnel, the GiPiS GPS navigator is able to recapture signals within 5 to 10 seconds upon exiting the tunnel in most cases.
