“…These advances have further led to the growth of relative guidance and navigation sensor technologies such as light detection and ranging 4,5 (LIDAR), laser dynamics range imager 6,7 (LDRI), and optical sensors combined with structured active light sources. These advances have tried to address the many well-known shortcomings of the GPS and VGS technologies.…”

An output feedback structured model reference adaptive control law has been developed for spacecraft rendezvous and docking problems. The effect of bounded output errors on controller performance is studied in detail. Output errors can represent an aggregation of sensor calibration errors, systematic bias, or some stochastic disturbances present in any real sensor measurements or state estimates. The performance of the control laws for stable, bounded tracking of the relative position and attitude trajectories is evaluated, considering unmodeled external as well as parametric disturbances and realistic position and attitude measurement errors. Essential ideas and results from computer simulations are presented to illustrate the performance of the algorithm developed in the paper.

“…This capability is a benefit when compared to a skin-tracking radar system or a lidar that provides only range and bearing to the centroid of the target. A similar, but simpler, technique has been used earlier to demonstrate the capture of a sample canister in Mars orbit using only a lidar [3].…”

Rendezvous lidar sensor system for terminal rendezvous, capture, and berthing to the International Space Station

The Rendezvous Lidar System (RLS), a high-performance scanning time-of-flight lidar jointly developed by MDA and Optech, was employed successfully during the XSS-11 spacecraft's 23-month mission. Ongoing development of the RLS mission software has resulted in an integrated pose functionality suited to safety-critical applications, specifically the terminal rendezvous of a visiting vehicle with the International Space Station (ISS). This integrated pose capability extends the contribution of the lidar from long-range acquisition and tracking for terminal rendezvous through to final alignment for docking or berthing. Innovative aspects of the technology that were developed include: 1) efficacious algorithms to detect, recognize, and compute the pose of a client spacecraft from a single scan using an intelligent search of candidate solutions, 2) automatic scene evaluation and feature selection algorithms and software that assist mission planners in specifying accurate and robust scan scheduling, and 3) optimal pose tracking functionality using knowledge of the relative spacecraft states. The development process incorporated the concept of sensor system bandwidth to address the sometimes unclear or misleading specifications of update rate and measurement delay often cited for rendezvous sensors. Because relative navigation sensors provide the measured feedback to the spacecraft GN&C, we propose a new method of specifying the performance of these sensors to better enable a full assessment of a given sensor in the closed-loop control for any given vehicle. This approach, and the tools and methods enabling it, permitted a rapid and rigorous development and verification of the pose tracking functionality. The complete system was then integrated and demonstrated in the MDA space vision facility using the flight-representative engineering model RLS lidar sensor.

“…Through monitoring the sensor outputs, most of the faults in the chaser spacecraft can be have already identified LIDAR as a preferred candidate instrument for autonomous rendezvous. It seems to be a justified and robust device for the mission success [31]. Moreover, the problem of fault diagnosis of multiple sensor faults occurring in the chaser spacecraft has been already addressed in the literature [32].…”

This paper deals with performance and reliability evaluation of a fault diagnosis scheme based on two distinct models to detect and isolate a single thruster fault affecting a chasing spacecraft during rendezvous with a passive target in a circular orbit. The analysis is conducted in the frame of a terminal rendezvous sequence of the Mars Sample Return mission. A complete description of a robust residual generation design approach based on eigenstructure assignment is presented.Unknowntime-varying delays, induced by the thruster drive electronics and uncertainties on thruster rise times, are considered as unknown inputs. Particular novelty of the work is a new method for estimating the unknown input directions used to enhance the robustness properties of the diagnosis scheme. Monte Carlo results from a high-fidelity industrial simulator and carefully selected performance and reliability indices allows us to evaluate the effectiveness of both schemes. The obtained results reveal that the proposed fault diagnosis scheme based on a position model is a justified competitor to the conventionally used attitude model-based scheme.
