High Altitude Ballooning
Calgary and Area
"Poor Mans Space program"
The payload is the science instruments of the project. My goal is to test the following in a payload:
- Radio transmission of position/sensors in CW - Radio transmission of position/sensors in Fuzzy modes Like Field Hell - Radio transmission of position/sensors in a light digital mode like RTTY - Radio transmission of position/sensors in APRS - Image Data stored on craft A long distance attempt will be made using simple hardware (micro payload) with no recovery. The power source will be solar and it will use mylar balloons.
Using the following: - Computer for data processing - GPS and/or RDF for position - Radio (CW and/or FM) - Internal Temp - External Temp - Atmopsheric Pressure - Digital Camera
Currently we have 2 Payload Designs:
Macro Payload: Latex Balloon with larger payload containing: cameras (to take pictures of near space), GPS data transmission as well as temp and hopefully pressure data back to mobile units to track the balloon as it assents and falls. Recovery is high priority to retrieve equipment and images taken by the camera. (this will be using a full featured APRS setup) I have previously used rtrack-hab, but have switched to the cheaper TT4 with handheld radio which also includes two way radio. Cutdown is used with this setup. The following is a pic of this setup:
The 2014 payload designs are:
(Dual tracker with cutdown and camera approx mass under 900grams)
(Single Track with Cutdown approx mass under 500 grams)
Here is an old payload getting prep for launch:
GPS micro payload: This weighs in at 70grams including GPS, 9V litium battery and foam box, ready to fly: Transmits RTTY and field-hell, i could add morse code as well if i wanted to.
Micro Payload: Latex/foil Balloon with small (light) payload containing: low power radio transmitter, transmitting callsign and hopefully temp and pressure data as it assents. Test recovery with No GPS data. Using only radio direction equipment. Recovery is not likely. The previous project uses a microcontroller with CW output of the beacon. Previously I have also used Field Hell, see Micro-sat1. The next version of this payload will transmit: CW, Field-hell and RTTY. The hardware is simple, including a pic (ATTINY or ATMEGA these days) and a AM, FM or OSC transmitter. Here is a pic of this transmitter hardware:
