1. A sighting system comprising:
a cradle holding a sighting device having a line of sight;
a base supporting the cradle, the cradle being configured to make the sighting device pivot about at least one axis of rotation with respect to the base;
a first tilt sensor rigidly attached to the base;
a second tilt sensor rigidly attached to the sighting device;
a calculator; and
a connector configured to connect each of the first tilt sensor and the second tilt sensor to the calculator, the calculator being configured to measure a difference between measurements made by each of the first tilt sensor and the second tilt sensor to quantify a tilt angle between the base and the sighting device.
