Improve Your Sensor Image With Balance

August 12, 2020

This paper reviews the properties which inherently limit the image quality of a gimbal mounted optical imaging system. It further describes how image quality is degraded by external influences, particularly vibration, in the supporting vehicle. The primary emphasis is to quantify, through physical principals, and verify, through experimental demonstration, the degree of static balance required […]

Choosing the Right Gimbal Balance Machine

December 28, 2020

Choosing the Right Gimbal Balance Machine The two primary factors affecting selection of a Space Electronics Gimbal Balance Machine are weight of the gimbal and its unbalance tolerance. Maximum gimbal weight.   The machine must accommodate the maximum weight and size of the gimbals to be balanced. However, it should be no larger than necessary since large […]

Using a Spherical Air Bearing to Simulate Weightlessness

It is important to test the attitude control systems on satellites before they are launched in space. Traditionally this has been done by dropping the satellite, and firing the thrusters before the satellite makes a soft landing in a net. This method only allows a few seconds of testing and does not lend itself to […]

Center of Gravity Definition

Factors Affecting Center of Gravity What is Center of Gravity (CG)? The center of gravity (CG) location is the average location of all the weight of an object. The center of gravity is the balance point of an object, also expressed as the point where all the mass appears to be located. How to Calculate […]

Homemade Center of Gravity Instrument

Avoid the Pitfalls of Homemade Center of Gravity Instruments Making a center of gravity instrument does not seem insurmountable. Homemade solutions such as attaching a plate to 3 or 4 load cells can be done quite easily and at a seemingly low cost. But… – What is the REAL cost? – What accuracy will you […]
