We at Hiber [0] are working on an actual low-power solution, which will give the device a way to transmit once a day to a sattelite with a custom 144 bytes user payload. The device location is already encoded, so you can focus on filling those 144 bytes with anything you'd like. You'll have global coverage and a central system to extract the data.

- sgt 8y agoWe would like to evaluate this. Currently looking at Sigfox, space.fleet and others. I sent a message via the Hiber contact page.
- femto 8y agoYou might also be interested in http://myriota.com/ http://myriota.com/ It's essentially a long life "tag" (10 years depending on duty cycle) that can read sensors and go direct to satellite. Funded by Boeing. I'm not involved in the company, but in the last 20 years have regularly crossed paths with one of the founders at Information Theory conferences. He's a very smart guy.
- bborud 8y agoIf you want to experiment with LoRaWAN, we open sourced our Network Service: https://github.com/exploratoryengineering/congress https://github.com/exploratoryengineering/congress We also open sourced our module design (EE-02) that uses nRF52 as the MCU: https://github.com/ExploratoryEngineering/ee0x-hardware https://github.com/ExploratoryEngineering/ee0x-hardware You can buy the modules here, but I think stocks might be running low. (However, if anyone needs larger numbers of modules we can put you into contact with the factory we use for manufacturing them): https://shop.exploratory.engineering/ https://shop.exploratory.engineering/
- orion138 8y agoCan you recommend a good write up on LoraWan architecture? (Curious about the need for a network service). Cheers!
- bborud 8y agoThe LoraWAN spec is surprisingly good. Dense as a bucket of lead shot, but usable to write an implementation :-)). https://lora-alliance.org/sites/default/files/2018-04/lorawantm_specification_-v1.1.pdf https://lora-alliance.org/sites/default/files/2018-04/lorawa... The short version is that all the intelligence is in the Network Service. The gateways are mostly resposible for converting packets into RF and RF into packets. Gateways talk to the network service through some backhaul (ethernet, wifi, 4G etc). (The Network Service is implemented in Go. The frontend is in a separate repository and done in vue.js)
- MrQuincle 8y agoNice!! Cool that it's open hardware. What's your business model considering you don't want someone buying large numbers from you? :-)
- bborud 8y agoYou have no idea how often I am asked that :-) We work for a telco, and this was just a learning exercise to understand the opportunities and challenges with LPWA. While waiting for NB-IoT chipsets and network rollout. We mostly set up the shop to have a orderly way for people to get the devices from us if they want to experiment (free stuff has a tendency to end up lining people's drawers unused) We built everything from (and including) the devices to the applications, and everything inbetween minus the LoRa gateway. The attitude being "okay we can read a bunch of datasheets and PPT-decks, but we're not going know anything unless we get hands on". So we did. The modules were just to get the radio and MCU bits into a reusable module which we then used for about a dozen or so prototypes. We run Apache MyNewt on them (the EE-02 was actually used to develop LoRa support for MyNewt). Since Nordic Semiconductor are in the same building the nRF52 was a pretty obvious choice (I think we might have been the first customer). They make lovely chips. And I'm not getting paid to say that :-). We did think about building a gateway as well, but we felt it didn't add much to the exercise. And now? Now we are doing the whole exercise again for NB-IoT, but this time it is to apply what we've learnt. That being said: we plan to open source stuff in the future. Both hardware and software.
- walrus01 8y agoClaimed pole to pole coverage tells me this is based on an embedded Iridium SBD modem.
- diamondo25 8y agoNope, it is our home made solution, with our own frequencies and satellites.
- walrus01 8y agoWhat are the NORAD IDs for your satellites, and TLEs? edit: https://space.skyrocket.de/doc_sdat/hiber-1.htm https://space.skyrocket.de/doc_sdat/hiber-1.htm edit: https://www.satellitetoday.com/ground-systems/2018/08/08/dutch-hiber-to-build-lpgan-ground-station-for-new-ksat-satellites/ https://www.satellitetoday.com/ground-systems/2018/08/08/dut... Absolutely makes sense you're working with Kongsberg for earth station services, since their facilities are well positioned for uplink/downlink from polar orbit and highly inclined orbit LEO satellites.
- KaiserPro 8y agowith respect, iridium is not low power. even the small "IoT" modem https://www.iridium.com/products/iridium-core-9523/ https://www.iridium.com/products/iridium-core-9523/ requires 2.5 watts peak. even once a day, you're lucky to get a months worth of reports from anything less than 10whr battery. Especially if you are in an urban/sky contrained environment.
- diamondo25 8y agoWe are not running on Iridium, but our own satellites and frequencies.
- KaiserPro 8y agosorry yes, I should have read this first: https://support.hiber.global/hc/en-us/article_attachments/360003823774/HBR-DS-18003_LPGANmodem-shortForm_v1.1.pdf https://support.hiber.global/hc/en-us/article_attachments/36... transmit is on average 4.1 watts. I get that for satellites that's pretty low power, but that's still in the order of 30dbm (assuming losses). compare that to the peak of 23dbm for LTE-m or 14dbm for lora. Now the OP author doesn't seem to grasp that the reason bluetooth le can last so long/update so much is because its got a limited range. Hiber at a minimum has to reach 600km, more when the satellite is not directly above. LTE-M only has to reach a few KM at best, lora has tiny packets with low duty cycle.
- Uberphallus 8y agoHi, had a look at your tech, quite interesting, but saw no open positions, do you see any opening in the short-medium term?
- diamondo25 8y agoThats correct, however you can send your CV to maarten@hiber.global, the CTO.
