Constraints the max change allowed per tick to the harmonic notch center frequency
“Shot noise” fix
Changing notch coefficients by a lot results in a significant noise spike
What’s this look like on a big vehicle?
No impact on flight performance on any aircraft
How about the 10hz RPM source?
E.g. efi motor
Will work for rapid update ones
But not for something only called at 10Hz
UTC0018 - RemoteID update
Two releases in the last week
Key features for real production use are in place
Remote update of the public keys
Signed firmware checking on RemoteID firmware
Mavlink and dronecan parameters
Secure update of parameters
E.g. uas ids
Via forwarded telem link
Tridge wants to work with people trying to deploy, please contact if you are implementing
Signed-update stuff is in place
Released by tridge is only tester
Need a management plugin for MissionPlanner
To be used by vendor who has the private key for managing which features are turned on and off on the module
Dronecan_gui_tool patches for secure update is coming
reading-of-GPS for standalone stuff is coming
Option to get pos info directly from CANbus rather than from flight controller
Steve is working on using the ESP32 for receiving the Remote ID messages for testing
Roahl is working on documentation for his product so you know exactly what to do to tick all the boxes
Not legal for standard remote id in the US
No requirement for GCS location ATM
Only require broadcast anyway
Single parameter to specify regulatory domain?
Universal firmware that will do all of them
Tridge will need guidance for other regulatory domains
Firmware releases are signed
Lock-level 2 sets efuses on board for tamper-resistance
Permanent change on the board
Board can’t be updated via USB or jtag
CAN bug? Loses operator location?
Tridge has not reproduced yet
Thing can be built into a system and fitted and then do updates remotely
So a vehicle could have one of these things but not activated
Bluemark is only commercial-quality device around ATM
Jeff will have one out soon
First DoC we’ll know what “tamper resistant” means
Wire harness? Screws? Potting?
“We’ll know it when we see it”
FAA want more than a sticker
FAA will revoke a DoC if they see a youtube video showing how to bypass it
Already several videos floating around for drone-flyer hunting parties
Some people are fixing on size, others on cost
Whatever is submitted in next 6-10 weeks probably will not meet the requirements in 18 months because the target is going to move
FAA will get mad at youtube videos
DJI already have a DoC which relies on their app
GPS spoofing on phones?
Works but will fall on operator
Apple receive app for wifi might exist now
Apple won’t open up the bluetooth stack to make a receive app there
[10:24 AM]Jeff Wurzbach: that parameter for operator location needs to be protected, btw.
[10:24 AM]Jeff Wurzbach: 9/16/2023 is the date for broadcast RID
[10:28 AM]Jeff Wurzbach: no mic today
[10:34 AM]Peter Hall: I predict public operator position will result in lots of those how to vids.
[10:34 AM]Josh Henderson: lol doublesided tape
[10:36 AM]Peter Hall: double-sided tape to hold it in, aluminium tape to bypass?
[10:36 AM]Josh Henderson: shhhh…
[10:37 AM]Josh Henderson: there has been talk of having a mechanism such that an app must receive a signal with such a level of signal stregnth
[10:38 AM]mturnbull: a friend of mine i just mentioned that youtube-video-decl.-of-conformity-loss thing too brought up an interesting point: does that mean the ArduPilot RemoteID repo can’t make use of GitHub issues, if an issue that comes up allows bypass?
