P-B Electrostatic Dust Transportation due to Secondary Electron Emission and Surface Electric Field above the Lunar Terminator P-A Nanosatellite Constellation for 3D Ionosphere Mapping P-A*: Mission Report of a Double Langmuir Probe Onboard HORYU-IV Satellite Any satellite whose orbit passes through the terrestrial magnetosphere will encounter several plasma regimes with widely differing temperatures, densities and compositions. The spacecraft itself will act as a plasma probe; each surface element changes its potential until no net current flows between it and the plasma.

Introduction. The space radiation environment presents hazards to satellites and the services they provide by causing internal and surface charging, displacement damage, accumulated dose effects, etc., which have led to many documented satellite anomalies (e.g., Baker, , Fennell et al., , Frederickson, ).This chapter focuses on internal charging, which is one of the main causes

Satellite Anomalies and Electrostatic Surface Discharges by Yan Chun Wong Major, United States Marine Corps B.S., University of Arizona, Submitted in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN SYSTEMS TECHNOLOGY (SPACE SYSTEMS OPERATIONS) from the NAVAL POSTGRADUATE SCHOOL September ABSTRACT Various Satellite anomalies and electrostatic surface discharges.

Item Preview remove-circle Satellite anomalies and electrostatic surface discharges. by Wong, Yan Chun.;Olsen, Richard C. Publication date TZ National Security Internet Archive (NSIA) Electrostatic surface discharge (ESD), electron caused electromagnetic pulse (ECEMP), and single event upset (SEU) are the three most common anomaly producing mechanisms in space systems.

The plasma environment, such as in geosynchronous orbit, can cause differential charging of satellite components and lead to ESD's on satellite :// Various aspects of the space environment can cause on-orbit satellite anomalies.

Studies have shown that adverse interactions between the natural space environment and space systems can have deleterious consequences comparable to those caused by human or design errors.

Electrostatic surface discharges (ESD), electron caused electromagnetic pulse (ECEMP), and single event upset (SEU) .9W/abstract. Satellite equipment needs to be immune to electrostatic discharges (ESD) likely to occur in flight.

Testing the susceptibility against ESD on spacecraft equipment is therefore an important part of   A GEOSYNCHRONOUS SATELLITE ELECTROSTATIC DISCHARGE MODEL. A satellite may become charged due to different physical phenomenon.

The photoelectric effect (sunlight) may cause charging. If the satellite is orbiting in a high electron flux, it   attributable to electrostatic discharges (just one form of environmental interaction) have been (especially in geosynchronous orbit) can cause differential charging of satellite components on the surface of the vehicle.

Surface charging can exceed breakdown voltages, and The Spacecraft Environmental Anomalies Expert System has been Electrostatic discharge results from spacecraft charging, be it surface or internal. Once the generated electric field due to charging exceeds a certain threshold, an arc discharge occurs, generating an electromagnetic transient that couples into spacecraft electronics and causes spacecraft operational ://?wbdisable=true.

Discharges can introduce noise into the system, cause interference, cause serious component damage, cause a bit flip, or completely interrupt spacecraft operation9. At GEO, the intensity of high-energy electrons can penetrate spacecraft shielding, cause operational anomalies, and even lead to satellite failures D.

This chapter focuses on internal charging, which is one of the main causes of space environment-related anomalies (Koons et al., ).

Spacecraft Charging (also see Spacecraft Charging Flash animation) Spacecraft charging includes both surface charging and internal dielectric charging.

The source and design mitigation techniques are different for each. Spacecraft charging consequences have ranged from intermittent anomalous behavior up to catastrophic satellite   Surface Charging: Charged particles collect on satellite surfaces producing high voltages, damaging arcs (electrostatic discharges), and electromagnetic interference.

Richard C. Olsen Approved for public release; distribution unlimited 92 3 02 Spacecraft and satellites orbiting the Earth are exposed to the electrostatic environments of the Earth's atmosphere. There are three main orbital regions around the Earth: low Earth orbit (LEO), medium Earth orbit (MEO), and geosynchronous Earth orbit (GEO).

LEO   argument, Spence et al. [2] mapped anomalies from a high inclination orbit and showed that the local time and L distribution mirrored the charging occurrences from near-geosynchronous satellites.

In this manner, they concluded that the anomalies were caused by satellite surface charging and resultant electrostatic ()pdf. Description. In space, satellites and spacecraft materials are vulnerable. They can become charged to tens or even thousands of volts when plasmas in the space environment interact with a spacecraft.

Spacecraft Charging explains this phenomenon while exploring the effects that energetic plasma has on the space environment and the objects within :// NASA’s Technical Handbook for Avoiding On-Orbit ESD Anomalies satellite.

The key distinction is that surface electrostatic discharges (ESDs) are often loosely coupled to the interior victim circuits. This handbook is concerned about electrons with sufficient energy to deposit close to a victim ?.

The calculated surface potentials on the satellite are critically reviewed, the possibility for electrostatic discharges (ESD) is analysed, and protective measures for the minimization of the Spacecraft surface charging induced by severe environments at geosynchronous orbit J.-C.
