manual Above.

Here's the Northstar technical bulletin if by any chance you were the last person to miss it. http://www.northstarnav.com/About/Ne...-Announcement/

Could well be faulty connector installation . When you turn it on do all the intial self-tests say Passed or OK, including GPS Rx Self-Test" & "Beacon RX Self-Test"? (You can use the Star key to access the Service Information page to review the results & SW versions if you missed it at start-up.) If so , when it is trying to acquire sufficient number of satellites to lock on in 3D is the Sat page showing any satellites being fully acquired. Is the unit showing the proper date?

Fwiw- the latest and last ever Main Board SW version is 4.10 I beleive- released many years ago.

If it is a 951 XD ( there would be a "D" on the end of the ser. # on back of the 951 & on the Service Info page mentioned above) , does the differential station lock on with good SNR ?( If not, try switching manual input of your usual DGPS station's frequency and baud rate you ma have recorded in your log. Access is thru Star key "Receiver Options page, Beacon Frequency & Baud Rate (ie., Acushnet,MA is 306 KHZ at 200 baud .) You should be able to acquire the satellites without DGPS lock but sometimes punching that in in Manual mode can actually help.http://www.navcen.uscg.gov/navinfo/d...tusBySite.aspx

When you get the Acquire or Sky Search message at the top of the GPS Position scree hit the Star Key once and then the Clear Alarm soft button. That won't hurry anything along towards lock but at least that Exclamation point alarm icon should stop flashng at you.

You might use the Star key to find the Time Of Day page and ensure yours is set for the correct Eastern time zone and confirm "Daylight" is not on or showing (until Mar 13 for 2010.) Not sure about these Northstars but some GPS's will look for the wrong satellites in the wrong place if initial time zone & DST setting is incorrectly input.

Make sure radar and other electronics are off to rule out interference. It supposedly should only take 2-5 minutes to acquire "cold" but I've had my 952's take up to 45 minutes to settle down an lock on during 1st installation of the season if the set was moved even a few miles since last on , then were OK after that.

Sometimes it can really be a faulty antenna of course . The 951's self-test should indicate if an internal board was bad. I doubt a slightly shorter cable is critical.



Just found a note in my manual from the N/S techs (it may depend uopon which antenna you have):
Antenna problems?
1. Disconnect antenna leads & measure voltage from inner wire to external ground. 2.The GPS BNC connector should have ~ 5 vdc
3. The DGPS PL-259 connector should have 7.5 vdc.

Check, the antenna resistance, also ensure that ALL software is updated.

However N/S does have available the 19.75 mb software download
http://www.northstarnav.com/en/Downl...tware-Updates/ ,

and the GPS to PC loader cable is Northstar # 1100-LC which also supposedly works with their Waypoint Loader downloadable program

http://www.northstarnav.com/en/Downloads/ .

I have the #1100-LC cable I think I bought long ago from N/S and can see a label on it that has that same part # , plus "rev A", plus "L-tronics", so I would suggest giving these folks a call to see if they would sell direct:
http://l-tronics.com/ . Has a plastic 18-female pin connector on one end to connect to the 951/952 and a metal serial (I think) port connector on the computer end , so you might also need a serial/USB adapter for a late model notebook. .

Good luck, hope it works.

Versions to look for:

How do I track and get gps location on a cell phone for free when all I know is the number?


On an iPhone you have a Free App to download called Find iPhone.
Generally this is used for locating a lost or stolen iPhone, using another iPhone or Computer and with the ability to remotely play a sound to help locate the device or Delete all the Data on that iPhone remotely.
If you have 2 iPhones or more in a family and they share the same Apple ID Account that you use to purchase Apps (through iTunes) and to Manage & Backup your data & Apps. If both iPhones use the same Apple ID & Password then the "Find iPhone" App can be used to check and see the GPS position of the other iPhone on a map.
The tracking is not saveable as a file. Also www.icloud.com can be used to log in and see the location of all devices in the family (on the same Apple Account).
There is also an App called Find Friends that allows you to track friends current location but it does require & request their permission when first used.
You could also get a free App and install it on the other persons iPhone and simply have it running in the background to remember all GPS location data during a period of time. e.g. a "Pedometer" to track a persons movements. You would require access to the iPhone at some point to recover that data by plugging in to a computer using iTunes to recover the location data. Running some GPS Apps in the background will noticeably reduce the battery as all GPS tracking devices do.
Figure out the details by installing the Pedometer or iTrack App on your own phone first.

I have a Northstar 6000i that will not display the tide track information. It has for 3 years,and now has a message stating that it can't display the information for the current date.


Probably the data didn't go past 2010. I have a Northstar 951XD, and first time out this year, no more tide track data - my manual says it only went fron 1994 - 2010. So how to get updates?

Tracking storage options GPSMAP 295


Every waypoint in the track has date/time, altitude and position. Second and subsequent waypoints will enable calculation and display of leg length, time, speed and direction between each par of points. The track can be displayed in 3D; in Google Earth for example. As far as I know there is no way to change the interval.

Gps loses signal


It would be good to make sure that the 951 software is up to date. The most recent software upgrade includes new code required due to changes that have been made to the GPS system. You can download the software for free from the Northstar web site but it requires a loader cable, power supply and a Windows based PC to perform the update. Most Noprthstar dealers know how to do this but they will charge for their time. The GPS antenna should be mounted where it has a 360 degree uninhibited view of the sky right down to the horizon to get best performance. Basicially any conductive material including pigmented paint, tinted glass or wet canvas can block the signal. Inspect the GPS coaxial cable and it's connections for any signs of corrosion or contamination. Sometimes just removing and reinstalling the connections is enough to remove contamination and get better performance. If in doubt concerning the coax and it's connections, temporaily substitute a new coax assy by-passing the existing cable to see if this makes a difference. You can monitor changes from the GPS status page. See the user manual for information concerning how to understand the numbers being presented. You should be tracking at least 4 SATs with signal levels higher than 30. Generally 95% of all GPS signal issues are related to the coax or its connections.
