{% hint style="warning" %}
OSNMA cryptographic keys are not installed with the firmware. Users will be required to register on the [GSC website](https://www.gsc-europa.eu/) and enroll in the OSNMA service to acquire cryptographic keys.

At the time this article is written (2024/12/12), the Initial Service Declaration has not been made yet. Users can only acquire the OSNMA key by applying to the public observation test
