Big Red
BIG RED is ITR's first dual-stage rocket with a targeted altitude of 33,000ft. Initially built for the 2022 Spaceport America competition, "Big Red" stands slightly over 13 feet with a 4-inch diameter.
Big Red features NOVA, a STM32 custom flight computer designed and fabricated by ITR student, along with custom ground station for live telemetry and data analysis built from Python tkinter.
The rocket is a whopping 13.35 feet and weighs just under 60 pounds. The booster stage is equipped with AeroTech N2000W motor, and the second stage is equipped with an AeroTech M1780.
"Big Red" was ultimately launched at the Friends of Amateur Rocketry launch site in Mojave, California on December 16th, 2023
Avionics
Sustainer & Booster
All flight computers and supplementary electronics (Pull pin switches and batteries) are in the sustainer’s avionics bay, inside the sustainer’s dual-deployment coupling (mid-body length of the stage). The primary flight computer system consists of an AltusMetrum TeleMega, which has barometric and GPS altitude detection and is also responsible for igniting the sustainer motor. The backup flight computer consists of a Featherweight Altimeters Blue Raven, which has barometric altitude detection with no RF transmission.
Ground Station
The ground station also utilizes the dual-redundant setup for safety. The primary system consists of TeleBT paired with a 433 MHZ Yagi antenna connected to a laptop running AltOS software. The backup system consists of Baofang BF-F8HP with NA-771 antenna receiving APRS packets sending data to Android tablet using APRSdroid software.
