Cycle Slip Detection during High Ionospheric Activities Based on Combined Triple-Frequency GNSS Signals

A New Real-Time Cycle Slip Detection and Repair Method under High Ionospheric Activity for a Triple-Frequency GPS/BDS Receiver

Cycle slip detection and repair is a prerequisite for high-precision global navigation satellite system (GNSS)-based positioning. With the modernization and development of GNSS systems, more satellites are available to transmit triple-frequency signals, which allows the introduction of additional linear combinations and provides new opportunities for cycle slip detection and repair. In this pap...

Real-time Cycle Slip Detection and Repair for Network Multi-GNSS, Multi-frequency data processing

The GNSS community is experiencing a new era with the development of the multi-GNSS and multi-frequency industry. For high-precision GNSS data processing with the use of carrier phase measurements, quality control steps, such as, cycle slip detection and repair, are essential. With the correct detection and repair of the cycle slips, the carrier phase measurements will not be lumped by the unkn...

A New GNSS Single-Epoch Ambiguity Resolution Method Based on Triple-Frequency Signals

Fast and reliable ambiguity resolution (AR) has been a continuing challenge for real-time precise positioning based on dual-frequency Global Navigation Satellite Systems (GNSS) carrier phase observation. New GNSS systems (i.e., GPS modernization, BDS (BeiDou Navigation Satellite System), GLONASS (Global Navigation Satellite System), and Galileo) will provide multiple-frequency signals. The GNSS...

AATR an ionospheric activity indicator specifically based on GNSS measurements

This is anOp Abstract – This work reviews an ionospheric activity indicator useful for identifying disturbed periods affecting the performance ofGlobal Navigation Satellite System (GNSS). This index is based in the AlongArc TEC Rate (AATR) and can be easily computed from dual-frequency GNSS measurements. The AATR indicator has been assessed over more than one Solar Cycle (2002–2017) involving a...
