Static Navigation on ND-100S
« on: August 19, 2010, 01:58:10 pm »

What is Static Navigation?
Note – Static navigation is a position filter designed to be used with motor vehicles. When the vehicle’s velocity falls below a threshold, the position and heading are frozen, and velocity is set to zero. This condition will continue until the computed velocity rises above 1.2 times the threshold or until the computed position is at least a set distance from the frozen place. The threshold velocity and set distance may vary with software versions.

If the device doesn't update its location every now and then or it has to be move at a certain distance, possibly the Static Navigation feature is enabled. To fix this, please install this program: http://www.usglobalsat.com/store/downloads/SiRFDemo387.zip

Once you're done installing the said program, please follow the instructions below:

Use the provided cable and open up the Sirf Demo program.
Select the com port and set the baud rate to 4800. Click OK.
Choose Action > Open Data Source. Observe the scrolling data on the Debug View window.
Go to Action > Switch to SiRF Protocol. Look at the data on the Response View window.
Click on Navigation > Static Navigation. Select Disable and press Send.
Choose Action > Switch to NMEA Protocol. Under Baud rate, select 4800 and tap Send.
Observe the scrolling data back on the Debug View window.
Click Action > Open Data Source.
Close the program.
