Problems locking on satellites

Hi, I have a JRC NWZ4550 GPS. I've only used it once, I entered 3 way points and the system worked fine. Satellites lock on, all ok. I did a soft start, cleared the system, then started entering my way points. When I'd finished I went back to the satellite status page and found I had no satellites. All stations showed zero. I tried again then did a master reset, re-entered all info required, but still cant bring up any satellites. On starting testing says ok. I'm wondering if you can help me or put me on to someone who can advise me further. Thankyou

    I have read the manual and have looked for a service agent in South Australia, but there are none listed in the phone book.

Contact the maker of the GPS and see if there is a software Hotfix for this problem, i have a Garmin and it had the same issue, downloaded the new software and installed it and the problem was corrected, if it is not a software issue then u can be pretty sure the GPS is defective. FYI it can take up to 10 minutes to get a sat lock on any GPS, no matter the maker.

While driving Garmin Nuvi 250 constantly loses satellite signal. The screen says that it is aquiring a signal. It is also constantly refiguring the route.

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 then 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.

If you are running a 4310 aerial with this unit the aerial ran out of date sometime in August 2008. You will have to buy a jrc 124 aerial. I had the same problem. Check with the agent TMQ International.You will find that the unit won't keep the date you have entered in it to set it up, it goes back to the year 1989 on the satellite page.

Location is not shown correctly


everytime u turn the GPS device on it takes anywhere from 30secs to 4 mins to find and lock in the satellites . Once the satellites locked in it will be then start taking ur commands. In ur case u turned it off as u started driving and when u restarted it , it had a memory of where u turned it off and displayed u the location where u turned it off which was ur home, right, now if u would have waited till some satellites locked in , it would have then automatically displayed ur then current location. so next time when u start the unit (any GPS) wait till it locks in the satellites.

Regardless of which GPS unit you use, finding sufficient satellites can be difficult if you are working in an area with trees/mountains/hills or other obstacles. Here are some suggestions to locking onto satellites:

1.) Mission Planning. If you think you're going to be working in a tricky area, but sure to check mission planning. This software allows you to input a location and obstacles, and gives you the times when satellites will be best.

2.) Wait. It takes the GPS units varying amounts of time to "find" satellites, but if satellites are visible, the unit should lock on within 5 minutes.

3.) Move. If possible, move into an area that has a clearer view of the sky.

4.) Face south. This is especially important if you are using the GeoXT. Turn the GPS antenna so that it is facing the southern sky. The majority of satellites have their orbit so that they appear in our southern sky. There are also satellites in the east and west, and almost no satellites to the north.

5.) Rotate around. If facing south doesn't work, slowly rotate the GPS around 360 degrees.

Aquiring satellites


Are you outside with a clear view of the sky? It should find satellites once the unit is turned on. Does it say "Looking for satellites" or "Acquiring satellites"?

If it is "looking for satellites" then it means that the unit have lost all data (time, date, location). If it is "acquiring satellites" then it have date and time, but not location.

Looking for satellites require a longer setup time (could be as much as 15 minutes). Acquiring satellites is much faster (not more than 2 minutes).

Date and time is updated from satellites once the unit gets a satellite lock.

Garmin 60CSx - Cant find satellites


Try a re-load of the chipset driver. It is available from the Garmin website. I find that it occasionally becomes corrupt.
You can check by entering the "Main Menu" then "Setup" then "System" then press Menu and choose "Software Version".
If the "GPS SW Version" is 0.00 then a reload of the chipset driver will correct the problem.

Cheers.
