Antenna pointing

Antenna pointing devices and brackets for rapid top load repositioningAntenna pointing devices and brackets are available for different pointing functions. Made by Mastsystem, these antenna pointing devices and accessories are available with all colours and special paints that our masts systems. Designed and manufactured by us in Finland, these devices work optimally when paired with other Mastsystem products.We offer various types of in-house made antenna pointing solutions:RotatorsDouble rotatorsTiltersRotator-tiltersMade to stand time and extreme conditions, our manual antenna pointing devices are operated from the ground by manoeuvring ropes. Electric remote control units (24 VDC) are available for single rotators. For vehicle mounted masts, such as EXB and SkyHigh systems, we offer fully electric, computer controlled top load repositioning devices, supplied by trusted partner company.TR-masts can also be mounted on to a vehicleMounting: antennas and other top load types can be mounted either directly on the antenna pointing device, or with antenna specific adapters. We also design and manufacture customer specific antenna adapters.READ MORE ABOUT ANTENNA POSITIONING BY DOWNLOADING OUR PDF BELOW.

Time alternative that is designed for Class B/C applications. C20 Incremental Rotary Actuator Sierra Space in support of Earth observation satellites, has designed, developed, and delivered an Antenna Pointing Mechanism (APM) using the C20 Incremental Rotary Actuators (RA) for its axis drives. The C20 RAs are very low disturbance actuators, ideal for low jitter, high-resolution applications in an open-loop stepper motor driven system. C25 Incremental Rotary Actuator Sierra Space has developed a design for the C25 Incremental Rotary Actuator (RA) to meet the demands for a standard, low-cost, space-rated RA. Used for antenna pointing assemblies or for solar arrays to maintain proper tracking, these C25 RAs meet multiple application requirements with the same design. Micro Jitter Systems LDC20 Low-Disturbance Gimbal Sierra Space has developed an innovative bi-axis gimbal that sets new standards for low-disturbance, open-loop operation when paired with one of our microstepping drives. The gimbal has completed qualification and is available for critical spaceflight applications. Incremental Motion Actuation C14 Bi-Axis Gimbal Sierra Space offers a lightweight, bi-axial gimbal, featuring the C14 incremental rotary actuator developed specifically for critical spacecraft pointing applications. Originally developed for antenna pointing mechanisms on communications satellites, the device has also been adapted for solar array drives and is suitable for thruster or instrument pointing.

Originally developed for antenna pointing mechanisms on communications satellites, the device has also been adapted for solar array drives and is suitable for thruster or instrument pointing as well. C14E Bi-Axis Gimbal The Bi-Axis Gimbal was developed specifically for spacecraft pointing applications. The gimbal is based on the C14E rotary actuator. The actuator contains a permanent magnet stepper motor driving a harmonic drive. The motor and transmission are designed as free-standing units

Pointing Systems and Motion Control Sierra Space is an industry leader in precision, low disturbance pointing systems for space applications. We have developed several single- and dualaxis pointing systems for deploying and positioning antennae, solar array drives and mechanisms, optical telescopes, and instrument mechanisms. Each axis of the pointing system is typically driven by a precision rotary actuator, which features a redundant stepper motor, strain wave gearset and/or hybrid transmission, with various position telemetry options. The rotary actuator is configurable with multiple options, through holes for cable management, slip rings, twist capsules, radio frequency (RF) rotary joints, telemetry sensors and adjustable hard stops. The biaxial brackets have been designed for minimal orthogonal distortion, high stiffness, and low mass. Our pointing systems are qualified and flight-proven with NASA programs, commercial and military satellites, and the International Space Station (ISS).Although we specialize in custom-engineered open- and closed-loop solutions, our list of qualified motors, actuators, gimbals, and drive electronics has grown into a substantial portfolio that can support a wide range of applications and sizes with minimal nonrecurring effort required.

Stood over 20’ tall (comparable in size to an average family home) and was 1/3 the volume of the International Space Station. Test results exceeded NASA’s recommended x4 safety levels by 27%. We also conducted Accelerated Systematic sub scale (LIFE10) creep tests, which determined the maximum time that the softgoods structure could withstand high pressure to calculate overall life expectancy in years. Sierra Space’s and NASA’s suggested guideline targets were short and medium duration tests based on 100 and 1,000 hours, and our softgoods shell lasted well over 150 hours on the short duration and met the medium duration performance expectations, marking a huge step in the future of human space habitation. Our team is continuing to push the boundaries of the softgoods inflatable habitat technology by leveraging advancements in LIFE 10 (10 cubic meters) LIFE 285 (285 cubic meters) and now introducing LIFE 500 (500 cubic meters). We will continue to conduct test campaigns in 2024 and early 2025 by testing two LIFE 10, two… Continue Reading Building the World’s First Commercial Space Station C14 Bi-Axis Gimbal Sierra Space offers a lightweight, bi-axial gimbal, featuring the C14 incremental rotary actuator developed specifically for critical spacecraft pointing applications.
