This article discusses the attitude modes employed by present Global (and Regional) Navigation Satellite Systems (GNSSs) and models used to describe them along with definitions of constellation-specific spacecraft body frames. A uniform convention for labeling principal axes is proposed International GNSS Service (IGS), which results in a common formulation nominal all satellites yaw-steering mode irrespective their specific orbit constellation. The conventions defined within this document...
Although developed and optimised for open oceans, satellite altimetry has the potential to monitor level variations of inland surface waters such as lakes rivers. Here we present results water Amazon River based on eight years (1993–2000) data Topex/Poseidon satellite. We first discuss methods detect wet surfaces from altimetric measurements, discriminate between dry land, quantify accuracy measurements over water. Then show fluctuations at selected locations where crosses River. The...
This study presents the results of 2013 Ibiza (Western Mediterranean) calibration campaign Jason-2 and SARAL altimeters. It took place from 14 to 16 September comprised two phases: GNSS (Global Navigation Satellite System) buoys estimate antenna height each them absolute altimeter bias (i.e., difference sea level measured by radar altimetry GNSS). The first one was achieved in harbor at a close vicinity tide gauge second performed ∼ 40 km northwest Island crossover point nominal...
The paper describes Romulux, a mobile robot equipped with 3D LiDAR carrying an illuminance meter and dedicated to measure indoor lighting quantity. aim is check compliance standards in terms of level uniformity. general architecture the using Robot Operating System (ROS) presented, technical choices are explained according different constraints. space localization data computed Synchronous Localization And Mapping (SLAM) algorithms. Then measurements compared requirements interpolated into...
We demonstrate in this paper that satellite altimeter data resolve the drop Aral Sea level during 1993–2000 of about 0.6 m per year resulting a change surface area from 35000 to 22000 km 2 and volume 270 130 3 . The sudden sea Northern basin on 04.21.1999 dam break‐up is also clearly resolved. temporal spatial variability reveals response patterns which are characteristic for friction dominated shallow dynamics. combination salinity sea‐level enables identify major events environmental...
Abstract. Water resources management relies on the use of hydrometric data collected mainly from in situ stations. Despite efforts made setting up and maintaining a network meteorological stations, water resource managers face many problems, such as equipment degradation during floods, incidents vandalism issues related to inaccessibility. Satellite can improve monitoring, regardless its objectives (strategic resources, structures, forecasting floods low flows, etc.). These have advantage...
This paper presents a navigation approach for autonomous agricultural robots based on LiDAR data. is divided into two parts: line finding algorithm and control algorithm. The proposes several algorithms (based PEARL/Ruby approach) that extract lines from data set. Once the have been processed set, filters these and, using fuzzy controller, generates wheel speed commands to move robot among crop rows. was tested simulator built ROS middle-ware Gazebo (the source codes of simulation are...
IstiABot is a mobile robot made for education and research purposes. This aims to be modular, easy modify used by first year students as well last researchers. To achieve those requirements, the built on top of CANBus Network. paper presents approach behind its building. It also an educational application platform (tuning PID controller) (Simultaneous Localization And Mapping - SLAM experimentations). Finally it concludes about this experience introduce two other robots that were based...
