Cycle slip detection and repair are crucial for precise GPS-derived orbit determination of the low-Earth orbit (LEO) satellites. We present a new approach to detect and repair cycle slips for dual-frequency LEO satellite GPS observations. According to Newton’s equation of motion. the second-order time difference of the LEO satellite’s position (STP) is only related to the ... https://www.chiggate.com/satisfyer-pro-penguin-next-generation-on-sale/
