3 SYMPTOM BASED FAULTS - NO FAULT CODES Can I utilize my DGPS Universal, DGPS 130, or DGPS EZ-Guide 110 Receiver with Omnistar HP differential signal? CAUSE No, Omnistar HP requires a L1/L2 GPS Receiver. EXPLANATION Omnistar HP real-time differential solution requires a L1/L2 carrier phase GPS receiver. The Ag252 is the only receiver that can utilize the Omnistar HP signal. The other receivers are L1 only receivers. These are sub-meter quality receivers. Best expected pass-to-pass performance when utilizing WAAS & Omnistar VBS is around 10 inches for both autoguidance and manual guidance systems. Pass-to-pass accuracy is based on a 15-minute time frame. Expected pass-to-pass accuracy when utilizing Omnistar HP is within 4 inches.

4 Low number of satellites when using RTK. Ag252 Receiver Guidance Cause Poor constellation of available satellites. Use the Planning Software to help manage poor operating times. How to use Planning Software. SOLUTION The Planning Software is an advanced software tool for analyzing satellite visibility based on almanac data. This powerful, stand-alone utility supports any form of visibility analysis for GPS satellites. Use Planning software to maximize your efficiency and monitor your work. Planning software can answer questions, such as: 1. When is the PDOP for a location less than x, and when are more than y satellites visible? 2. I want to run x base stations/tractors simultaneously. When do I have the best conditions for all of them? 3. I want to work during a given time span. How many satellites will be visible? 4. My location is partially obstructed by buildings or trees. Can I still expect good results? 5. Can I automate creating a visibility report for each day of the year? STEP 1 Downloading the software A. Go to the Trimble website, www.trimble.com/planningsoftware_ts.asp?Nav=Collection-8425. B. Click the Planning Software link. NOTE: The software is 22 MB in size and will take some time to download. C. Select the option to save the file to your computer. D. Select a folder to save the file to, then click Save. STEP 2 Installing the software A. Go to the folder you selected in Step 4 above, then double click the file SetupPlanning.exe. B. Select the language for installation, then follow the prompts. C. Once the software is installed, click Finish. D. Restart the computer. STEP 3 Downloading an ephemeris file A. An ephemeris file tells the Planning software where the satellites will be on a given day. It is recommended that you download a current ephemeris file at least once a week. The file must be less then 30 days old for the Planning software to use it. Trimble updates the ephemeris file on the website at least once a day. STEP 4 To download a current ephemeris: A. Go to the Trimble website (www.trimble.com/gpsdataresources.html), then click the Current Ephemeris Data link. B. Select the option to save the file to your computer. C. Save the file (Current.ssf) to the folder C:\My Documents.

5 STEP 5 Using the Planning software A. Use the Planning software to plan your field sessions. B. Click Start / Program / Trimble Office / Utilities / Planning. The Planning software starts. C. From the Almanac menu, select Clear. D. This clears the Almanac file to ensure you that are looking at the most current GPS satellites in the constellation when you import the SSF file in the next step. E. From the Almanac menu, select Import / SSF. The SSF Files dialog appears. F. Import the ephemeris file you just downloaded. By default, the dialog opens in the folder C:\My Documents. G. Select the Current.ssf file, then click Open. H. A message appears telling you that the Current.ssf file was successfully imported. Click OK to accept it. STEP 6 In the Satellite Systems toolbar, clear the GLONASS and WAAS check boxes. (Trimble Agriculture receivers do not support GLONASS.) STEP 7 Set up a station or reference location: A. Select File / Station. The following dialog appears: Enter the following:? B. Your position (or select a city) C. Your elevation cutoff (Set it to the elevation mask you are using in both the base and tractor receiver. The default in the RTK receivers is 13 degrees) D. The time and your time zone (so that the graphs will be accurate for your location) NOTE: The city you select should be within 30 miles (48KM) of your location. If the list of cities does not contain a city within close proximity to your location, you should enter a name and the position of your base station. The Planning software will save the name and position to the drop-down list of station names. E. Click Apply, then click OK to save your changes. F. From the Graphs menu, then select an appropriate graph to view. Use the Number of Satellites and DOP- Position graphs to determine the best time to work. The minimum number of satellites for working is four. However, you need five satellites to initiate the GPS RTK fix. Trimble recommends that you work with a minimum of five satellites. If you are in an area (field) that has tree lines, you will want to look for periods of the day that have more than five satellites to account for satellites that will be lost when the trees block the satellite signal. The GPS receiver you are using has a PDOP mask of 7. Therefore, look for values below 7 when determining working times. STEP 8 For more information on using the Planning software, select Help / Help Topics.

6 RTK GPS users are having problems obtaining or maintaining an RTK Fix due to inadequate satellite coverage in their location. Ag252 Receiver Guidance Cause A constellation change, a Satellite Vehicle (SV) out of service, and SVs low on the horizon being masked by natural or man-made structures can cause the number of satellites to drop below the required number for initializing or maintaining a fix. EXPLANATION Information on the causes of the low numbers of available satellites and provides instructions on how to plan your fieldwork around the time of day when adequate satellite coverage is available. Users cannot obtain or maintain an RTK fix due to inadequate satellite coverage. To initialize an RTK fix, five satellites are required. To maintain the RTK fix, four satellites in common are required. By default, RTK gps receivers have an elevation mask of 13. You can drop the elevation mask of the Base Station and Ag252 tractor gps receivers to 10 degrees for periods of minimal number of satellites without any noticeable change in accuracy. In some cases, dropping the elevation mask on both gps receivers just reduces the outage time and does not eliminate it. Where possible, plan you fieldwork around adequate satellite coverage using the Planning software.

7 RDL cannot read CompactFlash Data Card Remote Data Logger Cause The RDL may not be able to open or read CompactFlash data cards that have been formatted on computers running the Microsoft Windows 2000 or XP operating system. Solution Reformat the CompactFlash data card. Then copy all required files to the card in one operation to ensure that files are stored contiguously. The RDL may not recognize the basic format of the CompactFlash data card, for example, the number of sectors per track. The RDL may not find all the required files on the CompactFlash data card if the entries in the file directory are not contiguous. For example, files may have been added to or deleted from a CompactFlash data card at different times. This results in the files being stored in several different areas on the card. Even though this storage method is legitimate, the RDL reads only the first group of files that it finds. The best solution is to reformat the CompactFlash data card. Then copy all required files to the card in one operation to ensure that files are stored contiguously.

8 Losing Configuration Settings When the RDL is Powered Off. Remote Data Logger Cause The RDL’s configuration parameter settings are stored in battery-backed RAM (random access memory). The 9 volt battery has approximately a 1-year life span. Dead battery. Solution Replace 9v battery. The Remote Data Logger’s configuration parameter settings are stored in battery-backed RAM (random access memory). The 9 volt battery has approximately a 1-year life span. You can assume the alkaline battery has failed when the data logger no longer retains configuration parameter setting changes. A multi meter can be used to check the battery’s DC voltage level.The data logger can continue to use the default configuration parameters, but does not retain any changes to the default settings after it is powered off.

9 Trouble activating Omnistar VBS satellite differential subscriptions on Ag252 GPS Receiver. Cause Ag252 gps receiver can utilize both Omnistar VBS & Omnistar HP subscriptions. Solution When you request the activation code, make sure that you tell Omnistar that the Ag252 receiver is Omnistar HP capable. When you request an over the air activation code for your Ag252 receiver, you must tell them that the receiver is HP capable. Otherwise, you may have difficulty when you try to activate the Omnistar VBS subscription.
