Flight Test Updates

  • 2025-03-21 Flight Test (2025-3-21 Pegasus 2 Task 1 Sim w/ KML messages over MAVLink, Peggy Tuning, Task 2 Practice)

    • Peggy 2 Tuning

      • Very high winds, so only flew Harmonic Notch tuning data collection flights

      • Analysis and parameter changes to be done this week before next flight test @Manasva Katyal

    • Task 1 KML MAVLink messages test

      • Ran into connection issues again with the KML groundside script

        • Better version is in the works

      • However were able to fly the detection + geolocation part as well as extract the KML after the drone landed

        • Error analysis @Tochi Okoro

          • Was good! all below 3m (one was even 0.5m!!)

          • Flew at altitude 10m

    • Task 2 Payload test

      • Shortened the tubes to 2.1 meters

      • Flew another practice flight for inloading/offloading water

      • Quicker this time, both from a getting the tube into the bucket as well as loading perspective

    • Pathing

      • Flew this with Houston, was successful

    • More notes:

      • Flew pilot training for @Rohan Katreddy and @Rohaan Vasa on Houston

      • Tested tracking antenna

        • Tracking antenna itself worked (was just rotated by 180)

        • Houston had a crash during this, RCA @Yuchen Lin @Manasva Katyal @Evan Janakievski

Batteries

  • @Yuchen Lin

  • Battery cell went to zero, not is basically a 5s instead of 6

  • Moving to backup set

  • Label all bad batteries?

Task 1

  • PLANNING: Drone Swarm

    • Need to put in purchase request for another BetaFPV nano transmitter module, unless we see it being more beneficial to buy a new controller. $70 vs $160

      • Need to figure out what account too

  • STATUS: Autonomy Updates:

    • STATUS: MAVLink KML messages

      • @Tochi Okoro @Maxwell Lou

    • STATUS: Solutions to False Detections

      • This appears to be fixed, we had zero FPs at the last flight test

    • STATUS: Geolocation of Beacons

      • Error analysis from last flight test @Tochi Okoro

    • STATUS: Pathing

      • Were able to fly a basic 2 circle search pattern at 5m

      • To be made better by accounting for multi-drone operations and also looking into other patterns like a search spiral etc.

  • STATUS: Peggy 2 Tuning

    • Data collection complete for Harmonic Notch tuning

    • Will do MAGFit stuff at next flight test

    • Also might need to take a step back and do PID tuning again if we install extra pumps

      • More weight means current tune will become a little sluggish

  • STATUS: New Pi Interface PCBAs

    • Elected to assemble 3x last Saturday

    • ~90% SMT assembled, missing a few diodes. TH connectors to be added next.

    • Expected to finish assembly Tuesday EE work session, possibly time for validation

  • Beacons at different elevations

    • What if they are obscured for above?

  • Potential to fuse coords from drones by sending to one central computer

    • cc @Balaji Leninrajan

Task 2

  • STATUS: Flight Test Performance Analysis@Evan Janakievski

    • Flew quite well again, but with the high winds it was worrisome with it having to be near the ground and buckers

    • Was a lot quicker at getting the tubes into the bucket this time around. I have not watched footage yet, but felt a lot quicker when pumping in water vs the 3-meter tube

  • STATUS: Another Pump

    • Mech tasks are assigned. Double pump mount and a tank for supporting the new tubing

    • Aiming to have changes ready for first weekend of April

    • XT connectors on 6 new pumps for a total of 8 now

    •  

Other

  • STATUS: EFS CAN Lighting Board

    • In theory everything should be working, but need someone to plug stuff together and check - @Nick Armstrong

  • STATUS: Batteries Order

    • Email fwd’d, order to be placed (or maybe has already been placed by time of meeting)

    • Would be great if Ops is able to draft out an email to send to the people at Medicine Hat regarding the fact that they should expect a package for us @Emma Chan @Victoria Gee

    • Order has not been placed. Need it placed asap

  • STATUS: Cali Airframe

    • Needs a name

  • STATUS: x500 Holybro airframe

    • Needs a name

    • Will find out if we’ll fly it by townhall this week

  • PLANNING: Mission planner/Lua scripts for Task 1 and Task 2

    • @Evan Janakievski @Manasva Katyal bit overloaded at the moment

    • Would try and get the MP/script stuff ready for next FT

  • PLANNING: Tuning for Houston

    • Was not performed at last FT due to high winds

    • Postponed until Houston is brought up again

  • PLANNING: Transporting the drone

  • PLANNING: Proof of flight video

    • Will piece together from flight tests

    • Should have:

      • Take off

      • Approach and landing

      • Fly by

      • Hovering

    • To do:

      • VLOS traveling

      • Circles

  • STATUS: Registrations

    • @Manasva Katyal registered Peggy 2

      • Label to be made and attached to the drone

    • What other drones are we looking to register?

      • Likely would know this post townhall

 

Flight Test Planning

  • Will run a flight test this Friday

  • Flight test document to follow soon

  • Will be similar structure as previous tests as no major changes have occurred

  • Hoping to have MP and/or Lua scripts ready for testing and forming Task 2 flights

 

Asana

  • Look over asana dates and adjust/make updates
