Orbcomm frequency band
Webtransmitting at different frequency bands, making their signals diverse in frequency and direction [20]. To exploit LEO satellites for navigation, their positions and clock states, namely the clock bias and drift of the transmitter, must be known. The position of any satellite may be parameterized by its Keplerian elements: eccentricity, WebThe experimental results based on actual ORBCOMM signal show that the positioning accuracy can reach better than 140 m.The research of this paper is significant in theoretical research and...
