BluetoothLE RTK vs Field Master

1. Support GR-9029/GR-9028 Bluetooth LE GNSS receiver 2. App receive correction data from reference station and forward to receiver. 3. Receiver calculate the data and decide it's precision position, then send GGA to App 4.Finally App draw the position in map. App is a utility tool for testing the receiver. a.Relative position measurement GR-9029 have a button in it. User press the button ,then App will draw a pin in map. When user press again , the App draw a new pin and show the distance between two pin (If "distance measurement" function is enable) b. Absolute position measurement. Receiver is placed on a known position. User can compare the known position with the coordinate show in map. c.Benchmark with other receiver App support "Log" function , it can record entire path . User can compare the path with others and check the deviation

A camera tape measure, box volume, a bubble level, a noise meter and a scientific calculator in one app. Send what you measured as a one page report with a site photo. AR Distance and Volume Measure between two points with the camera. Before you place a point, a guide line and its length are shown, so you retake fewer measurements. Place four points and you get the volume too. Devices with LiDAR lock on more precisely, and you can switch between m, cm and ft. Bubble Level Lay the phone down for horizontal, stand it up and it switches to vertical by itself. The bubble rises to the high side just like a real one, and a 1 degree target, a 5 degree ring and a hint telling you which side is high make small tilts easy to see. A light vibration tells you when it is level. Noise Meter Read how loud it is right here in dB and keep it in the log. A colored scale shows at a glance whether it is quiet, normal, loud or harmful to your hearing. Log and Reports Values from the calculator, distance, volume, level and noise meter are saved with your notes. They group by date, you can search and filter by type, and export to CSV. Add a site name and a photo and build a one page report to send to a client or the office. Scientific Calculator Trigonometric and inverse trigonometric functions, logarithms, square root, square, reciprocal, factorial, percentage and sign change. Copy a result or save it straight to the log, and recall earlier results from the history. Quick Timer Start timing just by laying the phone down or standing it up, so it works with gloves on. Count down or count up, and it sounds when the time is done. About ads No feature is placed behind an ad. Nothing interrupts you while you measure a distance or check a level. Tap the chip at the top right of the home screen, watch one ad, and the banner stays away for the rest of the day. Seven Languages Korean, English, Japanese, Simplified and Traditional Chinese, Spanish and French, switchable inside the app at any time. Records stay on your device and are never sent to an outside server. No sign up is needed. AR measuring, the level and the noise meter give reference values from your phone's sensors. They are not certified measuring instruments and may be off, so when you need exact numbers, double check with a tape measure, a spirit level or a sound level meter.
