A Type-II Phase-Tracking Receiver [PDF]

open access: yesIEEE Journal of Solid-State Circuits, 2021
We present a new analog-to-digital converter (ADC)-based architecture of a phase-tracking receiver (PT-RX) optimized for ultra-low-power (ULP) and ultra-low-voltage (ULV) operations for the Internet of Things (IoT). The RX employs a type-II loop configuration that offers improved stability compared with the previous type-I PT-RX solutions. In addition,

Estimating and Analyzing Long-Term Multi-GNSS Inter-System Bias Based on Uncombined PPP

open access: yesSensors, 2020
With the development of precise positioning with multi-GNSS, the inter-system bias (ISB) has become an issue that cannot be ignored. ISB is introduced from the differences among satellite reference clocks and different receiver hardware delay biases.
