Hello,
I would like to fly with my drone in Brazil but I have never been in the country before and I don't speak Portugese so it's hard for me to find information about the allowed frequencies for drones. I'm interested in these frequencies : 433 Mhz, 915 Mhz, 1.3 Ghz, 2.4 Ghz, 5.8 Ghz
Please if you have some relevant information about frequencies, max. range, power restrictions, certification etc. let it share here. If I fly under 100m AGL, is there any restriction to fly (no airports obviously) ? Is the beyond-visual-line-of-sight allowed ? Does anyone care ? Any fines or problems with ANAC if I break rules ?
Thanks !
Michal

Aha so no approval for piloting, only for the equipment. But that can take ages right ? So if I want to fly 1 day, I still need approval of equipment before I fly right ? So is there some special person with email/telephone in Anatel who is responsible for this approval ?
Thanks !
Well,
is more complicated :)
Where are you intend to fly ?
Anatel is just for frequencies.
About flying, is another government agency called ANAC - they are responsible for aerial space and here they are discussing about what to do with VANTs
Here we have a controversial association called COBRA(http://www.cobra.org.br/) - I don't know about them - but some more experienced friends - since aeroplanes - they are always discussing about regulations and some guys are Ok with Cobra, some guys not.
While definitions is not coming, I'm still flying :)
Ah so a good old STATUS QUO as in my country.. I know regulatory agencies are very slow in issuing any rules at all so this all gets into the grey zone of free flying again :) My only concern is if the frequencies I want to use are banned or not. I mean if I use them, do I interfere with anyone else ? Especially in the fields/countryside outside the populated areas ? I guess not..
In 433 MHz maybe you start to open some folks garage door, but nothing too serious :) You can get a 10 dollars USB tv tuner and use it as a Software Defined Radio to check the spectrum on that particular location anyway.
Ops, just remembered, you SHOULD check the frequency use of 433MHz, my last employer had some projects with the army and I remember they requested 433MHz data modems.
Better be sure before you step on the boots of the buddies that have tanks and big guns.
All the civil UAV companies that I know in Brazil use 900MHz for telemetry and 2.4GHz for control. No problem with that on the "gray zone"
better to use 915 Mhz then.. I hope 2.4 Ghz for RC is not a problem.. I will try to check the 1.3 and 5.8 Ghz in place then.. Thanks
These frequencies are open, but not for UAV use. This is a limbo right now, if you want to play by the rule you can ask for a temporary permit to use a determined frequency on a limited area, but you are right, it'll take ages to get that.
The last ANAC meeting that I went with the presence of ANATEL they are talking about this:
Video data: 5030-5151 MHz
Telemetry, takeoff and landing: 4400-4429 MHz
Backup: 322-328 MHz
But this was just a draft of a proposal. Reference (portuguese only) http://www.dcabr.org.br/download/eventos/eventos-realizados/2010/se...
Thanks for the info. The document is 4 years old.. Anyway those frequencies you are talking about are useless for us.. If you want to use Pixhawk with telemetry (433/915), which frequency has better signal in your country ? I guess 915 Mhz should be OK since you are part of America..
Then for the RC most of the corrent ones use 2.4 Ghz so I hope this is OK because it's free wifi frequency anywhere in the world..
For the FPV I consider 1.3 Ghz and 5.8 Ghz because these are what's left to do not interfere with telemetry and RC..
