RE: Geometrics preliminary MagArrow and MagEx data processing program download   2 Relevance 1 year ago Ahmed Ramadan Software
  Hello Dear Rui, I have questions regarding MagArrow Magnetic data compensation, if you can answer please, 1- Does the heading error compensation that applied by surveying data processing program remove the heading effect due to direction only or calibrates the maneuver effect due to the swinging of the sensor as well? 2- Regarding the heading compensation flight, I am confused about the best Way to do this. In the manual, it is mentioned that we can apply a cloverleaf pattern (this is usually used in airborne survey) or a survey pattern or we can do a 360 degree turn at a certain point. However, it is written that we can use the calibration data measured in the turn, can I use the data from the turn to apply the heading error correction separately for each flight instead of doing a heading flight. Regarding the cloverleaf pattern application, is the data also processed in the same Way using surveying data processing program? 3-What is the importance of the base station magnetometer data in this correction as mentioned in the manual, I think we can apply it without base magnetometer? 4- Finally, is there a specific flight that can be done to make maneuver correction (FOM) (roll, pitch and yaw) that we apply in conventional magnetic airborne survey? or We just resort to the LP filter. Sorry for the long post Kind Regards, Ahmed

  @rzhang Thank you for sending the sample data in ASCII format. By the Way, since the output data is in binary format, what functionalities are implemented on the AUV and ASVs side for the connection? Are you using Windows OS on the AUV and ASVs, along with "MagView MagElement" or "MagElementLogger"?
Quick Download Process for the G-857 Magnetometer   1 Relevance 6 months ago Wei Jiang Hardware
  Verify BAUD Rate selected on dip switches 6,7,8 Note: according to a customer this is how the switches are set as they are attempting a file transfer at 115200 BAUD. Connect the G-857 to the computer using the download cable and a properly installed USB/RS-232 adaptor. (Must have FTDI): Open the MagMap Software. Select Import>G-857/ASCII 1. Enter known Serial Port (My computer is COM4) 2. BAUD 115200 (Switches 6, 7 and 8 off) 3. Set a good location for the file to written to. 4. Leave Download only, open later unchecked. 5. Leave download time out 2. Select OK. On the G-857 press OUTPUT, ENTER when this window opens. BYTES DOWNLOADED will begin to increment. Select OK in the window below: The downloaded Mag file should be displayed: If the download sequence does not happen this Way, it is usually a problem with: 1. USB/RS-232 Adaptor not FTDI, or driver not installed. 2. COM PORT assignment incorrect, and/or file destination not valid. 3. BAUD RATE mismatch. 4. Faulty I/O Cable PN 16492-01. 5.

Check to make sure that the G-857 is not in Legacy Mode: To check if Legacy Mode is enabled press: AUTO-OUTPUT To turn it off press: AUTO-OUTPUT-CLEAR To Turn on: AUTO-OUTPUT-ENTER If Legacy Mode was on then the recorded data recorded needs to be downloaded as a G-856:
What affects Geode trigger cycle times?   1 Relevance 8 months ago Kolby Pedrie Software
  What Affects Geode Trigger Cycle Times? If you're trying to optimize your Geode system for faster trigger cycles—especially in high-repeat environments—there are a few key factors to consider. The goal is to ensure that the system completes its entire cycle (trigger → recording → data transfer → re-arming) before the next expected trigger. Here’s what influences that cycle: 🧠 Core Factors That Affect Cycle Times 1. File Size (Sampling Parameters) Your sample interval and record length directly affect the size of each data file.You can view the resulting file size in the Acquisition Parameters menu.Larger files take longer to transfer, which delays the re-arm process. 2. Data Transfer Rate The Geode typically transfers data at around 450–465 kb/sec.Reducing file size is the best Way to reduce transfer time and speed up the cycle. 3. Calibration Frequency By default, the system may attempt to calibrate every N shots, which takes additional time.Go to Options > Calibration and set "calibrate every N shots" to a large number (e.g., 100000) to prevent unnecessary delays. 4. Recording Delay and Record Length If you're operating in a region with a consistently deep seafloor, you can add a recording delay and reduce record length accordingly.Example: If the water column is always >0.3s, you can apply a delay of 0.2s and reduce record length by the same amount.This trims your file size and speeds up the transfer/re-arm process. ⚙️ Best Practices Use the Auto-Trigger function or set trigger sensitivity to the maximum value for testing.Monitor the cycle timing and adjust acquisition parameters to stay within your trigger window.It's often an iterative process to find the ideal configuration for your environment.

Correct grounding technique for Geode seismographs   1 Relevance 1 year ago Anton Yuriev Hardware
  Hello, guys.I need to ask some questions about grounding technique for Geode seismographs. Current territory that we need to investigate has strong electromagnetic pollution from nearbuy high voltage power line. When using 48 to 96 geophones many channels experiencing strong EMI interference in wide spectrum. So I want to ask the forum society for some advices on the grounding technique of Geode modules. Because in documentation there is only a mention of "grounding plug" on the side of boxes. But there is no advices on how to properly ground 4 or more modules, distanced 240 meters from one another. Even more when soil has different properties along streamer line (moisture etc). On geometrics.com could not find any instructions on rightful grounding technique. Maybe there is exist some sort of special grounding schemes for large number of modules in use. As I understand the better Way is to have star topology for grounding (with one common rode point for several devices) when using spreaded device system. Because in other cases ground potential for different modules will vary. Maybe I asking a silly quastion but EMI problem anyway exist on long receivers arrays. That ruins noise/signal ratio and etc. Thanks.
RE: Geometrics preliminary MagArrow and MagEx data processing program download   1 Relevance 1 year ago Rui Zhang Software
  @ahmed_ramadan_geo Regarding your questions: 1. It removes the maneuver effect due to the swing of the sensor as well. 2. There are really NO best Way to do the compensation flight. There are two main requirements for a compensation flight: 1. Include as much roll/pitch/yaw motions as possible. 2. Avoid magnetic gradient. If you can fly the drone very high (>100m) over a low gradient area, a cloverleaf pattern is probably the best (as in traditional airborne surveys in which you can fly high to avoid the local gradient.). But this pattern is hard to fly, especially over a small area. 360-degree turn is simple and almost guaranteed to have no magnetic gradient in the compensation data since it is over the same location. If the MagArrow doesn't have much pitch and roll motion, 360-deg turn is sufficient. But it doesn't compensate well for pitch and roll maneuver noise (no much pitch/roll calibration). A survey pattern is between the two patterns described above. You may be able to use it, instead of doing a calibration flight. You can use the calibration file generation module to process the cloverleaf pattern. 3. Since the calibration flight is typically short, a base-station may not be necessary. Diurnal field change is usually not significant in a minute. 4. As I mentioned in 1., maneuver correction is also applied here. You can also use LP filter but make sure NOT to apply the heading compensation after the LP filter.
How do get live data streaming from UART5 or ethernet port without using MagView.   1 Relevance 2 years ago Kuldeep Dhiman Application
  Hi guys, I need MFAM live data streaming from ethernet or serial UART5 for my project. Initially, I am planning to write a piece of code using C++ that reads the data from one of the ports and prints it on the terminal. To be sure that data is present on UART5, I connected this port to the USB port of my laptop using a suitable cable and tried to monitor data using Putty with different baud rates but found nothing. Is data streaming available on UART5 by default? or do I need to enable it? I can see data on the ethernet port using MagView. Ethernet port uses TCP protocol. Is there any Way to enable UDP on the ethernet port? In case I write code to read the ethernet port using TCP then please suggest a suitable reference to start. Thanks a lot
RE: Sensor box SD card   1 Relevance 2 years ago Rui Zhang G-864
  @aldsantos For the current version of the embedded software, some raw data was first stored in the microSD and then transferred to the tablet. Data logging stops once the WIFI connection is lost. In the future, if we have an easier Way to access the microSD, we may use it as a backup.
Sensor box SD card   1 Relevance 2 years ago Andre Santos G-864
  I was doing a survey, and the tablet lost connection with the sensor, with no data being saved to the tablet. So I took the SD card of the sensor box, hoping that the data was kept there at least as a backup before the survey ended and data was completely transferred to the tablet. But there is nothing on the SD card. It is empty instead of having a LOST.DIR folder that is also empty.So, my question is, what is the sensor box SD card for?Second, is there a Way to prevent tablet disconnection from the sensor WIFI (which happens frequently) and backup data when this happens?
RE: How to measure with 2 MFAM systems in sync?   1 Relevance 2 years ago Rui Zhang Software
  Hi Martin, There is an easy Way to achieve this. You need to make another copy of the MagViewMFAM on the same computer, preferably in another folder. You can then open 2 MagViewMFAM programs. Let us know if you have other questions! Best Regards, Rui
How to measure with 2 MFAM systems in sync?   1 Relevance 2 years ago Martin Voelker Software
  Hello, we have 2 MFAM systems with 2 OPMs each, and would like to measure in sync. We saw that we can add a 1 PPS pulse as sync trigger when GPS is not available. But on Software side, MagView can only read from one system, and we could not figure out how to open 2 MagView instances on the same computer. (We would not like to use 2 computers...). Is there an easy Way how we can achieve this? Thanks in advance.
