Northstar 952 gps, will not acquire satellite signals,antenna, wire and connections look good.Worked 2 months ago.Fred 310-892-2453

Hello there,
As GPS units are used, data is gathered which helps them acquire satellites quickly at the start of each use. If a device is used daily it should be able to acquire satellites in a minute or less. Using a GPS device while it is outdoors with a clear view of the entire sky is the ideal condition for acquiring satellites. Please know that there can be several different factors that may cause a GPS unit to not acquire satellites:
If your unit is trying to acquire satellites for the first time, it may take longer than normal to establish an initial position. If the unit is powered on and outdoors with a clear view of the sky this should not take more than 3-5 minutes. If your unit has not been used for an extended period of time (more than a month), it may take 3-5 minutes to acquire satellites. If your unit is indoors, it may not acquire satellites. Even standing next to a window indoors will block a majority of the sky which is needed for a device to locate and lock onto a satellite signal. If you have just finished updating the software in your unit or you have performed a master reset, your unit may take 3-5 minutes to acquire while outdoors as the data that is used to locate satellites may have been erased. If your unit has traveled over 500 miles while turned off or not tracking your travel, it may take 3-5 minutes to acquire even in ideal conditions. If your vehicle has a protective coating on its windshield or electronic devices which interfere with the unit receiving signal, your unit may need an external antenna* in order to acquire satellites. If you suspect this to be an issue, try taking the unit outside of the vehicle with a clear view of the sky for 3-5 minutes so that the unit can acquire satellites. If your unit loses satellites once moved back into your vehicle you will most likely need an external antenna*. If your unit is still having trouble acquiring satellites, please ensure that it has the latest version of operating software by using our WebUpdater program. Once your unit is updated please allow the unit to acquire satellites outdoors in a stationary position with a clear view of the sky.
*Note: Some units may not be compatible with an external antenna. Please check the Compatible Devices tab on the external antenna's page to see if your unit is listed.
Hope this was helpful to you. Goodluck Elect_Comp

both the problems could be there mostly the chip corrupted.

If your unit is still acquiring satellite, then it means the signal strength is weak, try to get it outside where it can be facing the sky directly so it will be able to acquire satellite. Once you just update your gps receiver, it seems like it is brand new and when it wants to first acquire satellite, it might take longer to do so. But if it has access to the sky directly, it should take about 3 to 5 minutes to acquire.
If your unit is indoor, it may not acquire satellite, even if it is close to the window, it will not, but if it is outside, then it will acquire faster.
Check if you have any protective coating on your windshield or electronic devices which interfere with the unit from receiving signal from the satellite. Try to see if your gps receiver can use an antenna, then connect one to it and your gps will acquire satellite.
Try to reset your gps first before trying any other solution for the unit.

Good Luck. Did this help?

The error means it can't pick up valid GPS signals. In other words, bad reception.

Has the unit ever worked? Does the unit have an internal or external antenna? Are the batteries fully charged?

Try the unit outside with clear view of sky instead of in the car. This will give it the best chance of picking up a GPS signal.

If it still doesn't then suggest something broken inside.

This is an odd fix, but I read it yesterday after having the "Acquiring Signal" issue for a week. I put it in the freezer for 30 minutes, brought it back to my desk and now it works. I don't know why or how, but I am happy.

you can connect them by NMEA, but synchronize, no.

I experienced the same problem about acquiring satellite signal even when it's a clear sunny day. After 30 mintues, it was still searching! The unit appeared to have "stuck" in this acquiring mode. The following worked for me: 1) open the GPS antenna 2) press the bottom left screen while holding the power button to turn the unit on 3) enter maintenace mode 4) select diagnostics 5) clear error report, do NOT clear any user data 6) restart unit the usual way My GPS 350 was able to acquire satellite signal in less than 1 minute after the above steps were taken.
