    Sun Seek Video

    This is a brief video that demonstrates setting up the J-Mate and how the Sun Seek application works. You'll notice that from the time I put the solar filter on the J-Mate until the time I took it off, ready to collect points, required about 1 minute. No backsight required. Precision tests will...

    HPT435BT Radio Range in SE Oklahoma - DQPSK

    The antennas are now shipped pre-cut for a specific range of frequencies. I suspect you're fine if you are operating within the range of frequencies for the antenna that you purchased.

    bluetooth transfer

    Nothing to troubleshoot. It doesn't transfer files.

    SPCS2022

    This is partially true. I suspect that the GPS on Benchmark observations will help with possible future transformation software for transforming from NAVD88 to NAPG2022, but the NAPG2022 model is actually going to completely break away from using GPS on benchmarks for its development. As I...

    Sim card issues after Linux migration

    Did you try it in both SIM card slots, just to rule out that it's not a problem with the slot you are using?

    SPCS2022

    In the United States, a new reference frame is on the horizon. TRF 2022 and NAPG 2022 will replace the current NAD83 and NAVD. As part of this all States will have a new State Plane Coordinate System: SPCS2022. NGS has set for its policy and procedures for how the zones will be created. There...

    LS screen freeze

    @Michael Stazhkov are there any crash logs available that might explain why Mark's Triumph-LS screen is locking up?

    LS screen freeze

    What is the serial number for your LS?

    LS screen freeze

    There was an issue similar to what you describe that occurred when being near the base, like about 100' away, after starting it. If the user didn't press Done before walking away the LS would get bunched up trying to maintain the Bluetooth connection. The solution was to press Done before...

    LS screen freeze

    Press and hold A/V button recalibrates the touch screen. Any chance there were water droplets on the screen? Do the hardware buttons still work when it locks up?

    J-Tip Help

    I'm not sure. It's the same as the top plate for the rover pole if that helps.

    HPT435BT Radio Range in SE Oklahoma - DQPSK

    You want 5/8 5db gain. This is perfect for the HPT435BT also. The NGP in the 4db gain antenna stands for No Ground Plane.

    J-Tip Help

    It's proved to be very rugged. I've had mine fully submerged numerous times and it keeps on ticking. If I know I'm going to be picking up a lot of topo shots I will switch to the steel point and put the J-Tip in my vest pocket, but I don't coddle it at all. If 20% of my points are boundary and...

    J-Tip Help

    I keep it on the rover pole. Less to carry. On a clean site, I can carry the LS with a J-tip and my shovel and have all I need.

    Cool Pics

    I've taken the LS off the pole before and just shot it directly on top of the pipe, too. Lot's of ways to solve a problem. Makes surveying fun.

    Engines and Profiles

    It is very likely that you have a different general group profile for when you are using your RTN and when you are using your base. Changes made to the engines in one general group profile do not modify the settings for the engines in other general group profiles. So yes, you can have particular...

    J-Tip Help

    The compass is the most common thing I need to recalibrate. I find that I need to perhaps on a monthly basis. The J-Tip is a little less frequent, perhaps every few months. The tilt almost never.

    J-Tip Help

    Recalibrate compass when it stops pointing North. I test it by looking at the base rover statistics, which gives the direction to the base. I then point the LS at the base to make sure I see the same number (+/- the expected compass error of a few degrees). Recalibrate the J-Tip when it doesn't...
