Laser beam steering for GRACE Follow-On intersatellite interferometry.
The GRACE Follow-On satellites will use, for the first time, a Laser Ranging Interferometer to measure intersatellite distance changes from which fluctuations in Earth's geoid can be inferred. We have investigated the beam steering method that is required to maintain the laser link between the satellites. Although developed for the specific needs of the GRACE Follow-On mission, the beam steerin...
متن کاملExperimental demonstration of a self-tracking 16-aperture receive telescope array for laser intersatellite communications
An adaptive receive telescope array with 16 apertures has been designed and breadboarded. With respect to size and performance, such a telescope array is well suited for use as receive antenna in a coherent interorbit laser link. The laboratory demonstrator, designed to operate at a wavelength of = 1:064 m, is completely independent of any subsequent receiver and of the data modulation format e...
متن کاملIntersatellite laser ranging instrument for the GRACE follow-on mission
The Gravity Recovery and Climate Experiment (GRACE) has demonstrated that low–low satellite-tosatellite tracking enables monitoring the time variations of the Earth’s gravity field on a global scale, in particular those caused by mass-transport within the hydrosphere. Due to the importance of long-term continued monitoring of the variations of the Earth’s gravitational field and the limited lif...
متن کاملA low - noise TTL - corn pati ble
Low-noise lTL-compatible off-chip driver (OCD) circuits are very important, especially for low-power electronics, but scaled-down CMOS technology requires a lower operating voltage of 3.3 V, while most applications require 5 V. The dual power-supply requirement makes the design of OCD challenging, first because pull-up devices, especially p-MOS devices, must be able to handle an off-chip voltag...
