We're a group of Imperial College students, sending our first
payload up with a 1600g Hwoyee balloon tomorrow (Sunday 18/06/2016).
Unfortunately, our first launch try a few days ago, ended in vein as our
supplier delivered the needed helium to the wrong address, twice (on
two separate occasions). Thank you to all who were helping us listen and
we’re sorry that our launch didn’t take place for such a disappointing
reason. If you would be so kind as to help us track it again, we will be
launching tomorrow from Churchill college in Cambridge at approximately
11:00 am. We would appreciate any help in tracking our payload,
there'll be LORA 868 and 434, as well as RTTY 434 to listen to.
Payload ID IBMICLSentinel, RTTY, 434.250MHz, 850Hz shift, 300 baud, 8 N 2, SSDV and telemetry.
ID Sky1LoRa, LoRa, 869.850MHz, "Mode 1" Implicit mode, Error coding
4:5, Bandwidth 20.8kHz, SF 6, Low data rate optimize off SSDV and
Payload ID Sky2LoRa, LoRa, 434.750MHz, "Mode 1"
Implicit mode, Error coding 4:5, Bandwidth 20.8kHz, SF 6, Low data rate
optimize off SSDV and telemetry. Every 30 seconds Sky2LoRa listens for
incoming transmissions for 10 seconds.
We're also hoping we'll
be able to transmit tweets up to our payload for display on the on-board
screen. So if you want your tweets to show up high above the clouds
then please tweet us at @IBMICLSentinel with #tospace followed by your
message, alternatively tweet us #gethelp to get a list of commands back!
Many thanks from the Project Edge Team!
