Configuring Oscar as an Internet Base

  Configuring  Oscar  as an Internet Base Take DJI Phantom 4 RTK as an example Are you tired of any cons of UHF radio setup at the RTK base station? Or naturally, consider the NTRIP correction is proper for your  RTK applications? Within a few seconds by several simple button presses on the Oscar GNSS receiver's configuration panel, you are ready to connect any NTRIP capable rover receivers to the correction data stream broadcasted by the Oscar base station. 1. Configuring the Oscar Receiver 1.1 Connecting the receiver to the cellular network Internet 1) Insert a SIM card into the receiver. The sim card could be from any one of your local telecom operators. There is nothing special you need to worry about, e.g., a public or static IP address. Just be sure you have a data plan. 2) Turn on the cellular network connection over the configuration panel on the receiver. Use the two buttons on the panel to operate the menu shown on the OLED display. (For details of the operation over the

 What’s the Grid To Ground on Tersus Nuwa Tersus GNSS has recently developed the latest function, “Grid to Ground,” coordinate conversion on the Nuwa app. It greatly facilitates the conversion from GNSS survey results to optical survey results and the conversion between grid measurements on map data's projection surface and ground measurement coordinates. We can see from the picture below that Grid and Ground coordinates are mainly the coordinates located on two different planes. Suppose we have collected some GNSS points using a Tersus receiver, which is grid coordinates. We need to convert all points to ground coordinates. Just find a data point, for example, Pt1, calculate the combined scale factor of its location, apply the parameter to all grid points, and get the ground coordinates. To better understand the potential relationship between the two coordinate systems, we introduce several concepts as follows. 1. Direction offset Using an optical instrument to measure an unknown

Two survey modes to improve your efficiency Never Wrong Vs. Fixed Priority Tersus creatively provides two survey modes for users, never wrong (accuracy priority) and fixed priority. The never wrong (accuracy priority) mode guarantees the accuracy of customer’s survey points through strict threshold constraints, which is suitable for scenarios with high accuracy requirements such as RTK control survey; the fixed priority mode focuses on improving user measurement efficiency by seeking a balance between accuracy and the time required to get a fixed solution while satisfying the specification requirement of accuracy (RMS≤5cm). The Tersus R&D team controls the satellite searching status of the board through internal commands, including receiving different constellations, satellite altitude angles, signal-to-noise ratio satellites, and other forms by setting them to reproduce complex scenes such as half-sky, urban canyon, dense forest cover, and so on. And we statistically analyze the
Getting Off on the Wrong Foot The long-overdue sunset of an outdated conversion The article was first published on  amerisurv.com . BRIAN FISHER, PS 11.29.2020 Below is a classic surveying horror story that revolves mostly around the confusion of the Survey Foot (SFT) and the International Foot (IFT) definitions. Dr. Michael Dennis, PS, PE, the project manager for NGS’s 2022 State Plane Coordinate System (SPCS) project originally asked for stories about how SFT in an IFT state caused problems. This story was originally shared anonymously, and most of the details were left out, but because of public interest and so many follow up questions about how such a thing was technically possible we decided to tell more details about what happened. As with many stories of disaster, there isn’t exactly a single culprit, but more over a culture of behavior and sequence of several events that results finally in calamity. Some of them, in hindsight, are obvious, but please consider that at the time,

Oscar UltimateTilt Test Steps& Results Analysis

1. Tilt Test Steps  1) Configure Oscar Ultimate to rover mode and get a fixed solution. 2) Adjust the pole height; the default pole height is 1.8m in Nuwa. 3) Don't turn on the tilt button; measure a point in the "Survey" interface of Nuwa, then keep the pole tip at that point, rotate 90 degrees, and measure it again. Repeat three times to get four points in "Point" of Nuwa. 4) Compare the location of the four points in the "Survey" interface. If they're randomly distributed, and the distance between them is less than 2 cm, it means the pole is normal. If they are very regularly distributed and the distance between them is too large, please measure them four times again for confirmation. If the situation keeps the same, there may be something wrong with the ranging pole, better change to a good one. 5) Make sure the pole is no problem. Turn on the tilt button in Device-Nuwa 6) The tilt LED on the Oscar Ultimate OLED display lights on with steady re
