      RESEPI Camera is Not Shown in Interface

      Posted by Will Dillingham on May 21, 2021 3:32:20 AM

      Purpose: To provide solutions for why the RESEPI GUI is not displaying the camera.

      Last Updated: May 2021

      Before a flight, it is best to check the “Status” page of the RESEPI web GUI where the user should note that the LiDAR and camera are present like shown below.

      How Can I Estimate the LiDAR Point Density for My Flight?

      Posted by Luke Wilson on May 13, 2021 11:41:02 AM

      Purpose: To get a better understanding of the necessary distance between flight passes for your project.

      Last Updated: May 2021

      Firstly, it is important to note that the point density of a project is dependent on the following listed factors.

      • LiDAR scanner field of view
      • Flight AGL (Above Ground Level)
      • Flight Speed
      • LiDAR Scan Rate

      GNSS Correction Services for INS-DU

      Posted by Luke Wilson on Oct 5, 2020 2:15:15 PM

      Purpose: To understand the different GNSS correction services that can be used to enhance the performance and precision of the INS-DU.

      Last Updated: October 2020

      There are 2 different categories of GNSS correction services. These categories are based on either the State Space Representation (SSR) or Observation State Representations (OSR) of the errors. Both categories solve the same problem, but each use different techniques, delivery mechanisms, and core technologies to do so. Both SSR and OSR correction services are used to mitigate key GNSS errors (i.e. orbits, biases, clocks, etc.) in order to enable high precision GNSS performance.

      GNSS Signal, Correction, and Constellations

      Posted by Luke Wilson on Sep 23, 2020 5:43:55 PM

      Purpose: Global Navigation Satellite Systems (GNSS) such as GPS or BeiDou can sometimes have confusing terminology. This knowledge base document will explain some of the most commonly used terms regrading GNSS

      Last Updated: September 2020

      Constellation: A constellation is the collection of satellites that make up a particular system. Some examples of constellations are: GPS, BeiDou, Galileo, and GLONASS.

      Grounding of Your Device With a GNSS Receiver

      Posted by Luke Wilson on Aug 21, 2020 1:23:19 PM

      Purpose: To understand the grounding of an Inertial Labs device with a GNSS receiver and to understand the configuration of the TNC antenna cable shield.

      Last Updated: July 2020

      The shield of the TNC antenna cable is connected to the chassis of the device, and on the GNSS receiver this shield is connected to the power return potential. Since that is the case, the whole enclosure is under the same potential. We recommend users to isolate the chassis from the power return potential if it is required in their application, as we have not had any problems related to chassis isolation in any application.

      Manually Converting a .flash File to a .prm File

      Posted by Luke Wilson on Aug 20, 2020 1:49:29 PM

      Purpose: To understand how to convert a .flash file to .prm file.

      Last Updated: August 2020

      First, the user should open their .flash file in notepad++.

      Then, they should install “Hex-editor” plugin by going to the “Plugins” menu, then select “Plugins Admin”, then navigate to the “Available” tab, then click “Install”.

      Support Thread: The Window of the GUI is Smaller than Normal?

      Posted by Luke Wilson on Aug 20, 2020 1:25:19 PM

      Purpose: To provide a solution to bug that makes the toolbar containing icons smaller than it is supposed to be.

      Last Updated: July 2020

      When using the IMU GUI, it is possible that your window may appear as below. Note how the icon toolbar at the top is much smaller than it typically appears. The difference in the two windows can be seen in the image below.
