GPS PROBLEM SOLVING CHART

PROBLEM	POSSIBLE CAUSE	TRY THIS SOLUTION
GPS unit will not turn on	Bad power connection Batteries are dead	-Check all connections -Check to see if batteries are installed correctly -Replace with four new AA alkaline batteries.
Takes more than 10 minutes to get a position fix	Obstacles nearby interfering with view to satellites.	-Move to a new location. -Make sure antenna is pointing up, and has a clear view of the sky -Check Sat Status to see where the satellites are and if the receiver is collecting data. -If you have driven a long distance with the GPS unit turned off, it may take a while to locate satellites. This process may be sped up by going to Satellite Status page and pressing MENU, selecting New Location, and AUTOMATIC. This tells the GPS unit to look for different satellites and recalculate the satellite constellation.
GPS unit locks up or shuts down upon satellite lock	Firmware issue	Try shutting off the unit and turning it back on. If problem persists contact supervisor immediately to arrange for a replacement unit. The firmware needs to be updated by GIS staff.
You are in the middle of the woods but the GPS Map page shows you as being on some road	The Unit may be set to “snap to road”	On map page press Menu; select Setup Map, press enter; on the Map tab, scroll down to LOCK ON ROAD, press enter, select Off, press enter, press quit. Your unit will no longer center your location to the nearest road (useful mainly for car navigation)

Error Correction
Errors happen, we know that. From time to time your supervisor of trapping coordinator may ask for your help in resolving data errors. This is a list of errors you may encounter during the trapping season. There are other errors that the database still checks for but have become all but obsolete due to GPS units and data handling software. If you see a message not on this list that you do not understand, contact your database manager.
Invalid initials for agency – The database has no record of this trapper working for you. Most often this happens when a late hire’s information has not been passed along to your database manager. Also look for typos.
No site data found – Every planned site is preloaded to the database. There is a special routine to handle 9000 series random sites. If the database cannot match the record to a predetermined site, this error occurs. Check to make sure that the quad abbreviation and site number (or county/block/site) are correct and that this site is valid for the current year. Just because you trapped there last year, doesn’t mean we planned to do it this year.
Duplicate site in county/block – Another placement or omit record with the same county/block/site/state fields has already entered the database. In the case of two placements, evaluating the UTM coordinates can aid in determining if a site has been misnamed.
Duplicate site in quad – Another placement or omit record with the same quad/site/state fields has already entered the database. In the case of two placements, evaluating the UTM coordinates can aid in determining if a site has been misnamed.
Duplicate UTMs – The EXACT same easting and northing are already in the database. This error can occur with a duplicate site error or when a trapper enters two records at one location. If you cannot figure out what happened, contact your database manager for help. It is possible the other site is not in your agency.
Quad abbreviation/code invalid – The recorded quad abbreviation does not match an abbreviation know to the database. Check for typos.
Site number is zero – Just what it says. Sites are numbered with positive whole numbers.
Trap type invalid – Trap type must be “D”, “M” or “O”. All other letters are invalid.
Grid node outside quad – the gridnode coordinates for this site lie outside the bounds of the quad specified. Check to make sure the quad abbreviation and UTMs are correct.
Omit reason missing – The site has been omitted, but no reason given.

Record date later than current date – The date included in the record is later than the system date when the file is loaded.
Date invalid – The date string is not in a format that the database can read. Look for typos or misaligned data fields.
Catch Present, Trap Missing/Inaccessible – The trapper entered the trap condition “Missing” or “Inaccessible” and also entered a trap catch. BLACB0012MM000, for instance. Either the condition or the catch must be wrong, since you cannot count the moths in a trap you couldn’t find.
Catch value missing – The trapper failed to enter a catch for a trap reported as “Good” or “Damaged”.
Duplicate Inspection – Another inspection for this site, in the same state, on the same day has already entered the database. QC inspections do not cause this error when conducted on the same day as the trapper check. Often, either a QC was miscoded as a regular inspection or the trapper has submitted two records for the same inspection.
Duplicate final visit – A final visit inspection has already been recorded for this site. Since the trap is assumed removed from the field at final inspection, only one is allowed. A Final QC check will not duplicate a trapper’s regular final inspection.
Final visit before Midseason – The final date inside the final inspection record is earlier in the year than the date in the midseason record. This error has nothing to do with when, or in what order, the records were loaded into the database.
Inspection at omitted site – This site is in the database as omitted, therefore there should be no trap present to inspect. If the trap has been placed, submit a placement record and notify your database manager that the omit should be removed.
No trap placement record match – An inspection record has been submitted for a site that does not have a corresponding placement. If the inspection record has the correct county/block site or quad/site information, find the placement information from the trapper’s notes and submit a placement record.
Fail code missing or invalid – A QC inspection has failed a trap but did not include an acceptable failure reason.
QC Field Check code invalid – The record appears to be a QC inspection, but where the Pass or Fail code should be, there is something other than a “P” or “F”.
Trap condition invalid – Trap condition must be recorded as “D”, “G”, “I”, or “M”. All other letters are invalid.

Inspection too far – The UTMs recorded at inspection are greater than 200 meters from the reported placement UTMs. Double check that both the placement and inspection UTMs are what you believe they should be. Did you record the site number correctly? Did you wait until you got back to your car or were at the next trap site to record the inspection? We are testing this error in 2010 in an effort to determine if this variance is due to trapper habits or GPS signal quality. If you are absolutely certain you were at the correct location, recorded the GPS waypoint AT the trap and had a 3D satellite signal, let your supervisor know.
