In this paper, an approach is proposed for relative state estimation for satellites in formation flying. To estimate the relative states of two satellites, the kalman filter algorithms (ekf, ukf) are adopted with the relative range and range rate between two satellites and attitude of a satellite as measurement variables.
Relative orbit determination is widely used in the field of autonomously controlled satellite formation flying (sff). Currently, some traditional techniques cannot meet the strict requirement of the accuracy of relative orbit determination for certain space missions.
The formation of six telescopes and one hub must be able to operate on a baseline of 50 to 500 metres in a circular planar formation, and achieve a 1µm inter-satellite separation accuracy. A number of formation flying models have been developed to describe the relative.

The most straightforward relative navigation approach computes the satellite relative positions by differencing the absolute position vectors of each satellite in the formation. The state differencing method can be used to support decentralized, centralized, or hierarchical formation control strategies.
The satellite formation system [ 1] refers to a space system composed of multiple physically disconnected satellites in order to complete the same mission.

Satellite formation flying missions that are currently being planned. A good example here is the synthetic aperture radar (sar) interferometry formation consisting of the terrasar-x and tandem-x satellites. The primary mission objective here requires the relative position to be known within a 2 mm precision (1-dimensional).
For the docking maneuver, the relative distance is decreased to zero in a very slow and controlled manner.
It should be emphasized that a low-frequency array in space does not need to fix the relative satellite distances to within a fraction of a wavelength.
