The LOG-1 Altitude Logger is a flight recording system for rockets that allows for verification of flight simulations.
The LOG-1 is only 17mm across, meaning that it will fit into all high-power rockets and most hobby rockets.
With the ability to write on up to a 32GB MicroSD card and a user-selectable sampling rate, the LOG-1 can record more than 1 million flights before needing to offload data.
If the MicroSD card is not accessible based on the mounting of the LOG-1, all the data can be retrieved from the card through a UART connection.
All data from the flights are saved in a CSV file for easy data manipulation and presentation.
To preserve storage space and prevent clutter in data logs, 5 seconds of data are constantly recorded and deleted until a launch is detected, at which point it will save the data to the SD and begin logging directly to the file.
Over UART, multiple settings can be modified, including the sampling rate, the launch detection sensitivity, the type of filter used, and whether or not mach hardening is enabled.
To prevent unnecessary battery drain, the sampling rate can be set differently for ascent, descent, and post-landing.
