“…Pervan et al [1] and Gold and Brown [2] suggest a system using a relative GPS but GPS is subject to availability and is susceptible to jamming. Sierra Nevada Corp developed a RADAR based system called UAS common automatic recovery system (UCARS) [3] for relative pose estimation, it uses a millimeter wave radar on the ship in combination with a transponder on the UAV.…”

“…Saripalli [8] proposes a camera based method to land on moving objects but the motion constraints placed on the object and helicopter make the method unfit for shipdeck tracking. GPS [1], [2], [4], [5], [6] and radar [3] based methods involve installation of expensive infrastructure on-board the ship and require a data link between the rotorcraft and the shipdeck. The need for infrastructure on the ship renders carrier ships without the required equipment not landable.…”

Abstract-Shipdeck landing is one of the most challenging tasks for a rotorcraft. Current autonomous rotorcraft use shipdeck mounted transponders to measure the relative pose of the vehicle to the landing pad. This tracking system is not only expensive but renders an unequipped ship unlandable. We address the challenge of tracking shipdeck without additional infrastructure on the deck. We present two methods based on video and lidar that are able to track the shipdeck starting at a considerable distance from the ship. This redundant sensor design enables us to have two independent tracking systems. We show the results of the tracking algorithms in 3 different environments, 1. field testing results on actual helicopter flights, 2. in simulation with a moving shipdeck for lidar based tracking and 3. in laboratory using an occluded and moving scaled model of a landing deck for camera based tracking. The complimentary modalities allow shipdeck tracking under varying conditions.

PS revolutionized the field of navigation in the 1990s, and made precise navigation available to a wide array of users. Integration of GPS technology into the Shuttle avionics system also occurred in the 1990s. The planned use of GPS during Shuttle missions is not as extensive as some might expect, given the widespread use and success of GPS technology, and the availability of ~$100 receivers to the general public. The rationale behind the current planned use of GPS by the Shuttle Program is discussed along with some history and lessons learned. For the Shuttle Program to fully obtain the benefits of this technology, and to meet any future automation and autonomy requirements, a new GPS receiver with more advanced capabilities than the legacy unit may be needed. 1 II. Why GPS?As far back as the mid 1970s, the Shuttle Program seriously considered using GPS technology on the orbiters. 2 GPS technology had the potential to reduce the number of different types of navigation aids on the orbiter, and to make the orbiter more autonomous by providing self contained navigation on-orbit (reduce or eliminate the need for ground radar and Tracking and Data Relay Satellite (TDRS) tracking). However, the developmental nature of GPS technology, adequate performance of the existing Shuttle on-board and ground navigation systems and cost of GPS xx Copyright © 2004 by United Space Alliance, LLC.

A GPS Receiver Upgrade For The Space ShuttleRationale And ConsiderationsJohn L. Goodman * United Space Alliance LLC, Houston, TX 77058 In the mid 1990s, a 5 channel Global Positioning System (GPS) receiver was integrated into the Space Shuttle avionics system due to the anticipated start of Tactical Air Control and Navigation (TACAN) phase-out in the year 2000. While the early 1990s technology level receiver adds redundancy and flexibility to the navigation process, and improves safety at emergency landing sites, new capabilities in modern GPS receivers would further enhance Shuttle navigation. All-in-view satellite tracking, new GPS signals and ground and space based augmentation systems would provide a more robust GPS navigation solution for the orbiters, particularly if future missions call for automated landings, or on-board precision orbit determination. G integration and certification compared to the operational costs of the proven legacy systems drove the Shuttle Program to not incorporate GPS in the 1980s.By the early 1990s, with the GPS satellite...

“…Other approaches, e.g. by Michalson and Hua (1995), Pervan et al (1996Pervan et al ( , 2003 and Chang et al (2001) consider ambiguities as unknown variants in the positioning equations. These methods generate float ambiguities with no attempt to fix the integer values, making them unreliable due to the uncertainty in the ambiguity values.…”

Carrier phase-based integrity monitoring for high-accuracy positioning

et al. 2008

Pseudorange-based integrity monitoring, for example receiver autonomous integrity monitoring (RAIM), has been investigated for many years and is used in various applications such as non-precision approach phase of flight. However, for high-accuracy applications, carrier phase-based RAIM (CRAIM), an extension of pseudorange-based RAIM (PRAIM) must be used. Existing CRAIM algorithms are a direct extension of PRAIM in which the carrier phase ambiguities are estimated together with the estimation of the position solution. The main issues with the existing algorithms are reliability and robustness, which are dominated by the correctness of the ambiguity resolution, ambiguity validation and error sources such as multipath, cycle slips and noise correlation. This paper proposes a new carrier phase-based integrity monitoring algorithm for high-accuracy positioning, using a Kalman filter. The ambiguities are estimated together with other states in the Kalman filter. The double differenced pseudorange, widelane and carrier phase observations are used as measurements in the Kalman filter. This configuration makes the positioning solution both robust and reliable. The integrity monitoring is based on a number of test statistics and error propagation for the determination of the protection levels. The measurement noise and covariance matrices in the Kalman filter are used to account for the correlation due to differencing of measurements and in the construction of the test statistics. The coefficient used to project the test statistic to the position domain is derived and the synthesis of correlated noise errors is used to determine the protection level. Results from four cases based on limited real data injected with simulated cycle slips show that residual cycle slips have a negative impact on positioning accuracy and that the integrity monitoring algorithm proposed can be effective in detecting and isolating such occurrences if their effects violate the integrity requirements. The CRAIM algorithm proposed is suitable for use within Kalman filter-based integrated navigation systems.
