In comparison to other satellites, Jason-3 is smaller in size, only about 1 meter by 1 meter by 3.7 meters.

Similarly, DORIS is another system to help determine orbit positioning. Designed by CNES in France, DORIS uses the Doppler effect to base its system, which describes the differences in frequencies of waves between source and object. Thirdly, LRA (Laser Retroreflector Array) uses mirrors to track the time it takes for lasers to reach the Earth's surface and be reflected back, which can then be analyzed to understand the orbital positioning of Jason-3. These three techniques(GPS, DORIS, LRA) all aid in determining orbit height and positioning.
