High-density modulation shifts require precise RF environments, which the firmware maintains through dynamic power control. Allows the transmitter and receiver to operate on
Furthermore, the development process of the LTU-Rocket firmware highlights the importance of simulation and hardware-in-the-loop (HIL) testing. Because actual flight tests are expensive and high-risk, the firmware was extensively validated against simulated flight profiles. This allowed the engineering team to stress-test the code under thousands of simulated edge cases—ranging from motor over-pressurization to wind shear—before the hardware ever left the ground. This rigorous validation cycle transformed the firmware from a theoretical construct into a flight-proven asset.
: Sensor timestamps from different chips drifted. We now use the STM32’s master timer (TIM2) to latch external sensor data ready lines, giving us sub-microsecond alignment.

Modern LTU firmware allows the Rocket to transmit on one frequency and receive on another. This is invaluable in heavily congested 5 GHz environments, allowing operators to dodge localized interference on one side of the link. Duty Cycle Flexibility

Before the firmware existed, the team relied on "off-the-shelf" flight computers. These were reliable but limiting; they were black boxes that didn't allow the students to experiment with custom control algorithms or unique sensor arrays. To truly push the boundaries of aerospace engineering, the LTU students decided they needed to build their own—from the silicon up. The Development: Code Under Pressure
