Tracking algorithms for the GPS C/A code with an interference rejection capability based on state estimation technique are considered. A swept tone jamming signal is modeled as an autoregressive (AR) process and estimated jointly with the timing delay. A novel Mean-Value Theorem Particle Filter (MVT-PF) is applied to address the highly nonlinear measurement model and its performance is compared...

This paper studies how the home automation standard Tilidomotis (in the process of standardization) has been adapted to radio medium. Afrer presenting the Tilidomotis standard and concept, the paper highlights the constraints and characteristics of the radio medium in the 433 MHz ISM band. A protocol stack fitting these constraints is then introduced. The main characteristics of the low layer s...

The airborne telemetry environment presents unique challenges to end-to-end communications due to the highly dynamic topology and time-varying connectivity of high-velocity wireless nodes. The AeroTP transport protocol uses multiple reliability modes to trade off end-to-end reliability and efficiency as appropriate for different categories of telemetry data. Based on the architecture previously...

Networks of airborne nodes provide unique challenges to end-to-end communication, in particular due to the highly dynamic topology and time-varying connectivity of high velocity nodes, and unreliability of the wireless communication channel. This paper explores the issues and presents a design for a domainspecific transport protocol targeted to multihop network that interconnects high-velocity ...

The technical innovations of precise numerical radiometry, spectral differentiation and seasonally repetitive monitoring, introduced by the Landsat system, have created a new measurement approach to terrestrial monitoring. The Landsat-7 mission reflects significant progress in realizing the scientific potential of this measurement strategy. Substantial improvements in calibration procedures, bo...
