TimeTag.Space offers the first space-grade picosecond timing device, packing high precision, reliability and an attractive price point all into one. The technology has a long heritage of use in Satellite Laser Ranging (SLR), where it is used by more than half of the world's SLR stations. The adapted space timer is part of several ongoing ESA missions and private ventures, including the Luna 27 mission and the Hera planetary defense mission, among others.
