Exploring planets and asteroids with 6DoF sensors: Utopia and realism
(
- Earth, Planets and Space
, 2020-12-21)
A 6 degrees-of-freedom (6DoF) sensor, measuring three components of translational acceleration and three components of rotation rate, provides the full history of motion it is exposed to. In Earth sciences 6DoF sensors ...
Predictions of the geomagnetic secular variation based on the ensemble sequential assimilation of geomagnetic field models by dynamo simulations
(
- Earth, Planets and Space
, 2020-10-22)
The IGRF offers an important incentive for testing algorithms predicting the Earth’s magnetic field changes, known as secular variation (SV), in a 5-year range. Here, we present a SV candidate model for the 13th IGRF that ...
Constraints on Moon's Orbit 3.2 Billion Years Ago From Tidal Bundle Data
(
- Journal of Geophysical Research: Planets
, 2023-01-04)
The angular momentum of the Earth‐Moon system was initially dominated by Earth's rotation with a short solar day of around 5 hr duration. Since then, Earth gradually transferred angular momentum through tidal friction to ...
Impact of flex power on GPS Block IIF differential code biases
(
- GPS Solutions
, 2020-07-08)
GPS Block IIF satellites are able to redistribute the transmit power between the signal components. This ability is called flex power, and it has been developed as a remedy against jamming. Since it is operationally not ...
Lithospheric density structure of the southern Central Andes constrained by 3D data-integrative gravity modelling
(
- International Journal of Earth Sciences
, 2020-12-21)
The southern Central Andes (SCA) (between 27° S and 40° S) is bordered to the west by the convergent margin between the continental South American Plate and the oceanic Nazca Plate. The subduction angle along this margin ...
Considering different recent advancements in GNSS on real-time zenith troposphere estimates
(
- GPS Solutions
, 2020-07-30)
Global navigation satellite system (GNSS) remote sensing of the troposphere, called GNSS meteorology, is already a well-established tool in post-processing applications. Real-time GNSS meteorology has been possible since ...
On the possibility of getting traceable time and frequency measurements via GNSS receivers
(
- GPS Solutions
, 2020-09-02)
The realization of Coordinated Universal Time, one of the tasks of the International Bureau of Weights and Measures, relies on a network of international time links which currently is organized in a star-like scheme that ...
Performance of miniaturized atomic clocks in static laboratory and dynamic flight environments
(
- GPS Solutions
, 2020-10-13)
Miniaturized atomic clocks with high frequency stability as local oscillators in global navigation satellite system (GNSS) receivers promise to improve real-time kinematic applications. For a number of years, such oscillators ...
GPS + Galileo + BeiDou precise point positioning with triple-frequency ambiguity resolution
(
- GPS Solutions
, 2020-05-27)
Along with the rapid development of GNSS, not only BeiDou, but also Galileo, and the newly launched GPS satellites can provide signals on three frequencies at present. To fully take advantage of the multi-frequency ...
Impact of robot antenna calibration on dual-frequency smartphone-based high-accuracy positioning: a case study using the Huawei Mate20X
(
- GPS Solutions
, 2020-11-10)
The access to Android-based Global Navigation Satellite Systems (GNSS) raw measurements has become a strong motivation to investigate the feasibility of smartphone-based positioning. Since the beginning of this research, ...
