    We report a working prototype of absolute distance meter developed for outer-space operation by incorporating a fiber-type modelocked
    laser. The target distance is measured using a I GHz synthetic radio frequency (~0.3 m wavelength) provided by the 2rJh intermode
    harmonic of a 50 MHz pulse repetition rate. The measurement repeatability is 7 μm at I s averaging with an accuracy of ±20
    μm for a 2. 5 m target distance. With a I 00 Hz update rate, the measurement speed is fast enough to keep track of the target in motion
    with up to a I. 0 mis velocity. The prototype is built within a compact volume of A 4-size footprint to be feasible for the space mission
    of satellite-to-satellite distance measurement.
