CIRC 2023 GPS Beacon, and Night Task hardware/Software

Description

This is a variety of information to support the CIRC 2023 Night Task & Traversal Task

Usage during CIRC Search & Rescue task

To use the Astronaut GPS Beacon, connect to the open SSID "Isaac_Asimov"

• Astronaut IP will be accessible at http://10.10.11.1 Port 80
• Astronaut also accessible by Telnet at 10.10.11.1 Port 23
• Astronaut Beacon is a standard 802.11b/g/n 2.4Ghz access point on Channel 1
• See the Simulation folder in this repo for example output (GPS Beacon) Web/Telnet

To use the Reactor GPS Beacon, connect to the open SSID "Reactor"

• Reactor IP will be accessible at http://10.10.10.1 Port 80
• Reactor also accessible by Telnet at 10.10.10.1 Port 23
• Reactor hardware is a standard 802.11b/g/n 2.4Ghz access point on Channel 1
• See the Simulation folder in this repo for example output (GPS Beacon) Web/Telnet
  • There may be additional functionality/data added before event time permitting to assist teams
    • Telnet commands to test/start reactor
    • Separate webpage to test/start reactor
    • This page will be updated if so, as well as simulation folder
• CAD files provided
  • Reactor Module (URM) - May be used to confirm handling and gripping requirements
  • Reactor - May be used to test and confirm clearance
    • There is a minimum of 30mm between the reactor and module and housing wall for arm clearance
  • Control Panel - Can be used to test ability to manually press buttons if required

Usage during CIRC Search & Rescue task

To use the BLE Beacon, you will need a device that supports Bluetooth LE

• A great place to start for information
• The beacon in the field has an external antenna, using an ESP32-S3 module
• The antenna on the beacon is omnidirectional (Vertical Polarity).
  • Initial testing showed range of around 90M with Samsung S21 Ultra phone using Link
  • Some ability to roughly identify bearing would be convenient
• The beacon will broadcast at 1Hz, FSS (Spread Spectrum)
• Example code provided and is similar to code that will be on the device

Setting up your own hardware for testing

• The reactor and astronaut gps beacons are largely identical code-wise.
• The microcontroller used for all devices is a ESP-32-S3 Dev board you can view Here
  • The code is written in the arduino IDE, which means you can likely use the code on other hardware with wireless functionality. The code uses common libraries and a standard UART GPS module
  • Using the older common ESP32 WROOM/WROVER is likely code compatible.
• The BLE Beacon code is based on this Example
