USB GPS may be conflicted with other USB devices, especially the devices which need Com Ports from the computer, such as wireless cards. In this case, please uninstall the drivers of other devices first, then install the GPS driver to make it work. After that, you can install the drivers of other devices back to the computer.

The GPS requires a clear view of the sky. If you are indoors, or have the GPS located under a roof, overhang or dense foliage it is more difficult for the GPS to “see” the satellites. This impairs your signal. Move the GPS to an open spot. Fixing your position may take several minutes. Especially when using the Zenstar for the first time. After an extended of period of dormancy a longer time may be necessary to acquire a fix. This is because the internal battery requires charging before the GPS can obtain a good signal.
The Zenstar is a Global Positioning System receiver. Above us constantly, positioning satellites circle the earth sending signal information. GPS receivers process the signals and calculate their exact location by measuring the time difference from the satellites to determine accurate distances from the satellites. These points are triangulated to arrive at the location. A GPS receiver must have a clear view of the sky because it operates by line of sight with the satellites. A minimum of three satellites must be locked on to determine position and provide tracking ability. Your Zenstar communicates with your computer software with NMEA 0183 Interface Standard. This defines electrical signal requirements, data transmission protocol and time, and specific sentence formats. The software translates the GPS information to display your location on a geo-referenced chart.
The Zenstar GPS is designed to work with your computer and is compatible with all navigation software that requires a GPS with NMEA output. The following list is a sample of some of the programs that interface with the Zenstar GPS.
Marine Navigation Software
- Rose Point
- Ozi Explorer
Street Navigation Software
- Microsoft Streets & Trips
- Co-Pilot Travroute
- Delorme Street Atlas
Terrain Navigation Software
- Maptech Terrain Navigator
- Ozi Explorer
- Memory Map Navigator
WAAS PRN 122 and 134 satellites (in NMEA that is 35 and 47) were removed from service and replaced by PRNs 135 and 138 satellites (NMEA 48 and 51) back in July, 2007. Zenstar III GPS receiver has a search list in the code that determines which satellites it looks for, and if it can't find one, then goes through the rest of the list in order. The receiver previously had 122 and 134 at the top of its list. 135 and 138 were near the bottom of the list. So it takes time searching for 122 and then 134. Once it has exhausted the search with no results, the old versions firmware starts going through the entire list. It takes quite a while to find 135 or 138.
In order to get a quick WAAS signal (DGPS fix) of the new satellites, Zenstar III GPS receivers need to update the old version of GSW firmware to GSW 3.2.5. The new version of firmware will help the Zenstar III GPS receiver get a much quicker “DGPS fix”. Please note that the “DGPS fix” also depends on your location. If the WAAS signal is too weak in your location, you may not get “DGPS fix” or need a longer time to get GPS fix.
Today, the WAAS signal is not as important as before. There are more and more satellites in the sky and GPS has a much stronger ability to receive signals. Zenstar III GPS has 20 channels to receive satellite signals. It will pick up the strongest ones to get a fix. Therefore, it will get a position fix with very good accuracy whether you use WAAS satellites or not.
If you want to update your Zenstar III GPS receiver’s firmware to GSW 3.2.5, please contact us at email@example.com. We will help you update it.
