New user-selectable azimuth angles for SAR (Synthetic Aperture Radar) satellite tasking through Umbra. This feature offers much more control over SAR imaging. Our "pizza slice" tool shows you where the satellite will look from. Think of it like a flashlight shining on your target. Moving the slice lets you choose the best angle to see what you need, whether inside a building or in a deep valley. Check it out here: https://lnkd.in/gbiXBBR3 Also, explore SkyFi's PRO feature with Tasking Pass selection. It is available for individuals ($20/month) and organizations ($500/month). Key Benefits for azimuth angles: -Enhanced Flexibility: Choose satellite viewing angles to capture specific features and avoid shadowing. -Strategic Viewing: This technique is ideal for peering into hangars, under bridges, or down valleys. Our pizza-shaped selector visualizes the satellite's perspective. -Consistent Large-Area Imagery: Simplify mosaicking for seamless large-scale maps. -Improved Change Detection: Make temporal comparisons more accurate with consistent angles. -Industry-Specific Solutions: Customize imaging for unique sector requirements. -Geographical Challenge Navigation: Optimize data quality in complex terrains. #SARImaging #EarthObservation #SatelliteTechnology SkyFi

MUD® Solves SAR Data Gaps: Part 1 Radar SAR Interferometry is a well-established method used to measure movement and deformation on the Earth’s surface. By duplicating the orbital path, the precise time and geometry, successive radar signals are captured and analyzed for their differences. It is possible to detect movement or change, between captured images, as small as 2 mm. MUD® adds critical subsurface and underwater intelligence to traditional models and monitoring. #SAR #satellite #monitoring #technology #tailings #ThePowerOfMUD

Taking a magnetometery airborne survey with MagArrow (Geometrics) sensor. This sensor provides us with the ability to collect magnetic data continuously, with the optimal speed and resolution in geomagnetic surveys. (Of course, to make the video more exciting, I mixed the video recorded by the drone camera with a music😉)

TOPIC : AIRFIELD SURFACE MOVEMENT RADAR(ASMR) ASMR is limited in range to only a few miles, due to the high operating frequency of the system. It is highly vulnerable to precipiation interference, but offers sharp beamwidth from a small aerial. Specifications for ASMR typically resemble the following: wavelength = 3 cm PRI = 65 microseconds pulse width = 0.5 microseconds beamwidth = 0.5° aerial rotation = 75 RPM

I learned something! Linked is a concise and complete overview of sonar systems, in plain language! Great post!

New Publication https://lnkd.in/eezu9yND Comprehensive analysis of the influence of the number of blades of a helicopter rotor on the vibrations that are caused by the helicopter main rotor as well as the active reduction of these vibrations via individual blade control. To this end fundamental geometric relation within the helciopter rotor are evaluated resulting in the analysis of different types of vibration depending on the assumptions of each analysis. The investigation of vibrations resulting from random differences of the individual blades of the rotor leads to the generalized concept for in-flight tracking control using an individual blade control system which takes into account the practical challenges found in literature for this kind of control concept.

Dwell Fine is a first-in-the-world capability that delivers high-fidelity and high-resolution imagery, unique 25-second #SAR videos to analyze movements, and Color Sub-Aperture Images (CSI) which allow for an immediate indication of human-made objects and infrastructure. This — combined with the ability of ICEYE satellites to observe any location on Earth every few hours, day or night, and in any weather — enables a level of change detection that's never been possible before.

To set up a Real-Time Kinematic (RTK) system, you'll need a base station and a rover. The base station receives satellite signals and calculates corrections. The rover receives these corrections from the base station to improve its positioning accuracy. Remember, I'm not an expert, so it's always a good idea to consult a professional for detailed guidance. 😊🌐When carrying out a topographic survey, using a Real-Time Kinematic (RTK) system can provide precise positioning data. It helps in accurately mapping the terrain and capturing detailed topographic features. 🗺️📐
