“…This capability can be highly advantageous when signals are weaker, less stable, or at a different frequency than expected, and thus open-loop recording has been used in several deep space missions. 2) For example, it was used in a radio science mission of the Galileo probe during its entry into the Jovian atmosphere. 3) Additionally, the Mars Exploration Rovers used open-loop recording for communication during the entry, descent and landing phases.…”

The latest re-acquisition of IKAROS, which rebooted after hibernation mode, was achieved on April 23, 2015. In this re-acquisition, post-processing of open-loop tracking data was performed to search for IKAROS. The open-loop method enables signal processing, even under difficult communication conditions. The algorithm for processing open-loop tracking data is proposed and is applied for actual signal from IKAROS. It is demonstrated that the signal can be well analyzed by removing the Doppler shift effect because of the orbital and spinning motion of IKAROS, even when the signal is too weak to be acquired by real-time operation. Using the method proposed in this study, estimating the spinning motion of a spacecraft and acquiring various data are possible as well as detecting signal. This research can be applied not only to a spinning-type spacecraft, such as IKAROS, but also to those with uncertain attitudes.

“…Another method is to use radio waves to determine range and radial velocity (or range rate) 3 . The range is calculated by measuring the time it takes a tone to travel to the spacecraft and return to the ground (two-way ranging) and radial velocity is measured by capturing the Doppler shift inherent in the received signal (of an initially known frequency).…”

As the need grows for increased autonomy and position knowledge accuracy to support missions beyond Earth orbit, engineers must push and develop more advanced navigation sensors and systems that operate independent of Earth-based analysis and processing. Several spacecraft are approaching this problem using inter-spacecraft radiometric tracking and onboard autonomous optical navigation methods. This paper proposes an alternative implementation to aid in spacecraft position fixing. The proposed method Network-Based Navigation technique takes advantage of the communication data being sent between spacecraft and between spacecraft and ground control to embed navigation information. The navigation system uses these packets to provide navigation estimates to an onboard navigation filter to augment traditional ground-based radiometric tracking techniques. As opposed to using digital signal measurements to capture inherent information of the transmitted signal itself, this method relies on the embedded navigation packet headers to calculate a navigation estimate. This method is heavily dependent on clock accuracy and the initial results show the promising performance of a notional system. Nomenclature

“…They are used to obtain the residual group delay and residual delay rate in a conventional VLBI (Rogers, 1970). Only a few frequency components exist in each channel in NBV, and the search procedures between NBV and conventional VLBI are expected to be different (Takahashi et al, 2000;Thornton and Border, 2003). Coarse search is only used to obtain the residual delay rate in the current study, whereas fine delay search is employed to derive the phase delay of radio frequency (RF) carriers.…”

New method to resolve 2π ambiguity in NBV

et al. 2012

The Narrow Bandwidth VLBI (NBV) technique is utilized to track spacecrafts in Japanese lunar exploration. However, the problem of 2π ambiguity affects the phase delay of the carrier waves transmitted by satellites. A probabilistic algorithm called coarse search and fine delay search, in combination with a simple ambiguity judgment procedure, is presented in the current paper to resolve the 2π ambiguity. This method is employed to estimate both the delay and the delay rate from the residual phases obtained using NBV. Compared with previous analytic methods, it does not require strict constraint conditions. The ambiguity can be resolved even when the phase variations in the residual phase are 0.2 rad (approximately 11.6 degrees) compared with the less than 4.3 degree phase variations in the analytic method. The method also has the advantage of giving short time variations in the orbital motion of a satellite without ambiguity using NBV.
