“…It is therefore necessary to "electronically freeze" the range delay long enough to permit an integration to be performed. The result represents the range at the moment of freezing [28,29].…”

Our previous analyses of radio Doppler and ranging data from distant spacecraft in the solar system indicated that an apparent anomalous acceleration is acting on Pioneer 10 and 11, with a magnitude aP ∼ 8 × 10 −8 cm/s 2 , directed towards the Sun. Much effort has been expended looking for possible systematic origins of the residuals, but none has been found. A detailed investigation of effects both external to and internal to the spacecraft, as well as those due to modeling and computational techniques, is provided. We also discuss the methods, theoretical models, and experimental techniques used to detect and study small forces acting on interplanetary spacecraft. These include the methods of radio Doppler data collection, data editing, and data reduction.There is now further data for the Pioneer 10 orbit determination.

“…Literature studies have shown that the Doppler spread can be measured and estimated if the transmitter oscillator is stable [15]. However, the relative speed between each spacecraft, and between the spacecraft and ground station varies at all times.…”

“…Although the Doppler spread for spacecraft application has been widely studied for Doppler spread estimation and tracking purposes [15,21,22], most studies focus on either improving the spacecraft navigation [23] or the spacecraft communication [24]. This study focuses on the Doppler effects for SBSP wireless transmission.…”

“…However, the spacecraft travels at a higher orbital speed at LEO, and each spacecraft in LEO formation experiences different relative velocity to the ground station (or the leader spacecraft). If either option 1 or 2 is used, the received signal by either the leader spacecraft or the ground station experiences different Doppler effects [15]. Launching the SBSP spacecraft into GEO could eliminate the Doppler effect issue; however, huge spacecraft structures and high altitude orbits result in a higher wireless power transmission loss, and a higher implementation and maintenance costs [10,16,17].…”

The space-based solar power (SBSP) concept was introduced during the 1970s. However, the technological challenges during that period stalled its development. Decaying natural energy resources, global warming, and geopolitical pressures have encouraged many countries and researchers to seek new reliable energy sources, such as SBSP. A solar power technology that comprises low Earth orbit (LEO) spacecraft formation has been proposed in the literature. All spacecraft in the LEO formation harvest solar energy and transmit the power to a leader spacecraft or the ground station simultaneously. In the proposed LEO technique, the high and varying relative speed within the spacecraft formation, and also within the spacecraft and the Earth, causes a nonhomogeneous Doppler spread during solar power transmission. This Doppler spread reduces SBSP power transmission efficiency. In this paper, first, the transmission link budget from LEO and geostationary orbits to the Earth are compared, and the harvested energy by the ground station on the Earth is investigated. This motivates low or mid Earth orbit satellite usage for SBSP. Next, considering different spacecraft configurations, the impact of the distance between each spacecraft and the ground station, and the distance between each spacecraft and the leader spacecraft on the variation of the Doppler frequency spread is investigated. In addition, the impact of the position of the leader spacecraft with respect to other spacecraft in the formation is studied. The results confirm that higher altitude or Manuscript smaller formation size leads to lower Doppler frequency spread in the transmission between each spacecraft to the ground station (or leader spacecraft). Finally, several possible techniques to improve the wireless power transmission efficiency due to the Doppler effect are discussed and compared.

With the development of the space exploration missions, a practical and reliable capability for autonomous navigation is urgently needed to reduce operation cost, to improve operational e ciency and to increase mission safety by avoiding dangerous delay in ground control. Celestial navigation is a very attractive autonomous navigation solution for the space exploration missions. It suits LEO satellites as well as high earth orbit (HEO) satellites and deep space explorers. In this paper, a comprehensive overview of the current state and future trend of celestial navigation methods for three types of space explorers are introduced, which include satellites, deep space probes and planetary rovers.
