Questions About GPS

Find answers to common questions about GPS.

What is GPS?

GPS stands for Global Positioning System, which is a system that uses a series of 24

geosynchronous satellites to provide location data.

GPS satellites transmit signals to equipment on the ground. GPS receivers passively receive

satellite signals, but do not transmit.

Where Can I Use GPS?

GPS works wherever you have line-of-sight access to the GPS satellites.

How Do I Enable or Disable GPS?

By default, GPS is disabled. To enable GPS, see Enabling / Disabling GPS.

What are some GPS Limitations?

Weather conditions or tall nearby buildings may affect your ability to get a clear view of the

satellites and thus to acquire a GPS fix.

How Can I Stream GPS Data to Use With a Third-party GPS

Application?

GPS NMEA data is streamed over Wi-Fi or over a tethered USB connection using a virtual COM

port.

Follow these steps to stream NMEA data for a third-party GPS application.

1. Set GPS Mode to Continuous. (See Setting the GPS Mode.)

2. Determine the COM port number that your NETGEAR device (that is, your NETGEAR

Mingle Mobile Hotspot) is using.

In the following example for Windows, the Device Manager shows that COM 16 is used.

In your case, the COM port number might be different.

(If you don't know how to access the Device Manager, see

http://kb.netgear.com/app/answers/detail/a_id/22868.)

3. Configure your GPS application to use the same COM port. For help, see the

documentation of the GPS application.
