and outputs IMU data at 1 kHz. It offers a dynamic accuracy of better than 0.3° in heading and 0.1° in pitch and roll. Air speed is measured with a pitot- static system, as might be expected, but C-Astral has added a practical little detail to maintain its accuracy: a pair of transparent rubber tubes that reveal any dirt in the system and are easily pulled off to allow the user to blow it through with compressed air. It’s a design fix that emerged from early operational experience, C-Astral’s CEO and co- founder Marko Peljhan says. C-Astral has developed its C3P (command, control, communications and planning) software specifically for the Bramor family, and it has evolved to incorporate 10 years of experience and more than 50,000 flight hours built up by customers, pilots and engineers.
