The new atmospheric entry guidance system resulted in an orbit determination paradigm shift during final approach when compared to previous Mars lander missions. The evolving orbit determination filter strategies during cruise are presented. Furthermore, results of calibration activities of dynamical models are presented. The atmospheric entry interface trajectory knowledge was significantly better than the original requirements, which enabled the very precise landing in Gale Crater. Keywords: Mars Science Laboratory, Curiosity, Mars, Navigation, Orbit Determination 1. Introduction On August 6, 2012, the Mars Science Laboratory (MSL) and the Curiosity rover successful performed a precision landing in Gale Crater on Mars. A crucial part of the success was orbit determination (OD) during the cruise from Earth to Mars. The OD process involves determining the spacecraft state, predicting the future trajectory and characterizing the uncertainty associated with the predicted trajectory. This paper describes the orbit determination process, results, and unique challenges during the final approach phase.

  • Five Aerojet Boosters Set to Lift New Horizons Spacecraft
    January 15, 2006 Five Aerojet Boosters Set to Lift New Horizons Spacecraft Aerojet Propulsion Will Support Both Launch Vehicle and Spacecraft for Mission to Pluto SACRAMENTO, Calif., Jan. 15 /PRNewswire/ -- Aerojet, a GenCorp Inc. (NYSE: GY) company, will provide five solid rocket boosters for the launch vehicle and a propulsion system for the spacecraft when a Lockheed Martin Atlas® V launches the Pluto New Horizons spacecraft January 17 from Cape Canaveral, AFB. The launch window opens at 1:24 p.m. EST on January 17 and extends through February 14. The New Horizons mission, dubbed by NASA as the "first mission to the last planet," will study Pluto and its moon, Charon, in detail during a five-month- long flyby encounter. Pluto is the solar system's most distant planet, averaging 3.6 billion miles from the sun. Aerojet's solid rocket boosters (SRBs), each 67-feet long and providing an average of 250,000 pounds of thrust, will provide the necessary added thrust for the New Horizons mission. The SRBs have flown in previous vehicle configurations using two and three boosters; this is the first flight utilizing the five boosters. Additionally, 12 Aerojet monopropellant (hydrazine) thrusters on the Atlas V Centaur upper stage will provide roll, pitch, and yaw control settling burns for the launch vehicle main engines. Aerojet also supplies 8 retro rockets for Atlas Centaur separation. Aerojet also provided the spacecraft propulsion system, comprised of a propellant tank, 16 thrusters and various other components, which will control pointing and navigation for the spacecraft on its journey and during encounters with Pluto- Charon and, as part of a possible extended mission, to more distant, smaller objects in the Kuiper Belt.

  • Chapter 2 Tests of Magnetometer/Sun-Sensor Orbit Determination Using Flight Data*
    Chapter 2 Tests of Magnetometer/Sun-Sensor Orbit Determination Using Flight Data* 2.1 Introduction Orbit determination is an old topic in celestial mechanics and is an essential part of satellite navigation. Traditional ground-based tracking methods that use range and range-rate measurements can provide an orbit accuracy as good as a few centimeters1. Autonomous orbit determination using only onboard measurements can be a requirement of military satellites in order to guarantee independence from ground facilities2. The rapid increase in the number of satellites also increases the need for autonomous navigation because of bottlenecks in ground tracking facilities3. A filter that uses magnetometer measurements provides one possible means of doing autonomous orbit determination. This idea was first introduced by Psiaki and Martel4 and has been tested by a number of researchers since then3,5-9. Magnetometers fly on most spacecraft (S/C) for attitude determination and control purposes. Therefore, successful autonomous orbit determination using magnetometer measurements can make the integration of attitude and orbit determination possible and lead to reduced mission costs. Although magnetometer-based autonomous orbit determination is unlikely to have better accuracy than ground-based tracking, a magnetometer-based system could be applied to a mission that does not need the accuracy of ground-station tracking. The Tropical Rainfall Measurement Mission * This chapter is from the published paper: Hee Jung and Mark L. Psiaki, “Tests of Magnetometer/Sun-Sensor Orbit Determination Using Flight Data,” Journal of Guidance, Control, and Dynamics, Volume 25, Number 3, pp. 582-590. [© 2002.

In the course of this plan some anomalies have been found that cannot, in principle, be explained in the context of the most accurate orbital models including all known effects from classical dynamics and general relativity. Of particular interest for its puzzling nature, and the lack of any accepted explanation for the moment, is the flyby anomaly discov- ered in some spacecraft flybys of the Earth over the course of twenty years. This anomaly manifest itself as the impossibility of matching the pre and post-encounter Doppler tracking and ranging data within a single orbit but, on the contrary, a difference of a few mm/s in the asymptotic velocities is required to perform the fitting. Nevertheless, no dedicated missions have been carried out to eluci- arXiv:1711.08893v2 [astro-ph.EP] 13 Dec 2017 date the origin of this phenomenon with the objective either of revising our understanding of gravity or to improve the accuracy of spacecraft Doppler tracking by revealing a conventional origin.
