[06:51] <bertrik> it's so cool to see people are actually starting to use TheThingsNetwork now for balloon tracking :)
[06:53] <Darkside> so i was looing into this
[06:54] <Darkside> and i was reading 30 seconds of traffic per day?
[06:56] <bertrik> Darkside: yes, that's their recommendation ...
[06:56] <bertrik> the radio rules generally say 1% of the time on a particular frequency IIRC, but TTN likes to keep it even lower than that
[06:57] <Darkside> but a HAB would need to use a lot more than that
[06:57] <Darkside> if you want reasonable position updates
[06:59] <bertrik> depending on the lora spreading factor, the data rate is a lot faster than 50 baud, and you can use more than one frequency
[07:00] <Darkside> hmm
[07:02] <bertrik> I admit there doesn't seem to be a lot of margin in the packet rate

[07:06] OZ7EMA (~emanuel_@151.36.228.23) left irc: Ping timeout: 248 seconds
[07:10] <bekir_turkey> I think they dont use HF frequencies which has very long range propagation capability.
[07:13] OZ7EMA_ (~emanuel_@5.170.8.55) left irc: Quit: Textual IRC Client: www.textualapp.com
[07:14] <bertrik> bekir_turkey: it uses the 868 MHz band
[07:15] <bertrik> most common for RTTY is 434 MHz band
[07:15] <bertrik> and that too is limited by the radio horizon
[07:15] <bekir_turkey> Yes. For HAB, it is very limited.
[07:16] <bertrik> no, not really limited, you can reach hundreds of kilometers if you're in a balloon
[07:17] <SpacenearUS> New vehicle on the map: 03SP3KPH - 12https://tracker.habhub.org/#!qm=All&q=SP3KPH
[07:18] <bekir_turkey> Over USA or Europe yes. But over mid-asia or other places, will be difficult to track a balloon.
[07:18] <Darkside> yes, for circumnavigation flights HF is probably the better choice
[07:18] <Darkside> but i don tthink bertrik is talkig about those kind of flights
[07:22] <bertrik> if you want worldwide coverage, then it's not so easy indeed
[07:23] <bertrik> in april a cubesat was launched with a lora transceiver onboard + some other new semtech wideband modulation
[07:23] <bertrik> but you get only 14 minutes per day of visibility if I understood correctly
[07:23] <Darkside> theres a bunch of IoT cubesat things going on
[07:24] <bertrik> http://lacuna.space/
[07:24] <Darkside> Fleet space is doing it, Myriota is doing it
[07:24] <Darkside> etc
[07:25] <bekir_turkey> is this cubesat accessible with Lora device from ground ?
[07:26] <bertrik> it's only an experimental cubesat I think and bandwidth is probably very limited

[09:00] <bertrik> Darkside: this one is currently being tracked by TheThingsNetwork https://tracker.habhub.org/#!mt=roadmap&mz=9&qm=1_day&f=sp9uob-ttn&q=!RS_*;
[09:01] <Darkside> how often is it transmitting?
[09:01] <Darkside> often it seems!
[09:02] <Darkside> jeez look at all the ground stations
[09:02] <Darkside> i take it your code is adding the ground stations in as they receive the telemetry
[09:05] <bertrik> Darkside: yes, exactly
[09:06] <bertrik> from TTN I receive the payload + list of all stations that received it (with their GPS location)
[09:10] <Darkside> what's the tracker hardware in this case
[09:10] <Darkside> ?
[09:10] <Darkside> might look at doing somethign similar here! though definitely nnot as extensive a network!
[09:10] <bertrik> I don't know what the hardware is, I just wrote the TTN->habhub software
[09:12] <bertrik> you can do the LoRa radio modulation with an SX1276 chip and the LoRaWAN protocol stack can fit in an arduino like an STM32
[09:25] <bertrik> hm, it seems quite a few TTN gateway owners registered their gateway with 'unique id' 123456789ABCDEF' or something like that ...

[10:46] <Darkside> since theres no way to specify a full date in the telemetry sentence, only a time
[10:46] <Darkside> unless im missing something
[10:46] <daveake> Erm dunno
[11:08] <SA6BSS-Mike> I think sp9uon Tomaz is doing something similar
