How does an unattended ground sensor system work?
Unattended ground sensor systems are used to electronically detect the presence of personnel and vehicles and to monitor their movements. Sensor systems detect motion, sound, heat, and ferrous metal. When activated by an intrusion, sensors transmit a coded radio frequency message to a portable or base monitoring
How does a ground fault sensor work in a transformer?
Ground fault current is sensed by passing all lines carrying current to and from a motor through the window of a special current transformer called a ground fault sensor. If all of the current to the motor returns through the lines in the sensor window, no significant current will be induced in the sensor secondary.
How does grounding of a sensor reduce capacitance?
Removing the connection from the shield to system ground at the amplifier input and connecting the shield to the signal ground at the sensor as shown in Figure 7 reduces the effect of cable capacitance and prevents common mode current, Icm, from flowing through the signal source.
How does shielding and grounding work on a sensor?
The topology of such circuits tends to cancel certain types of noise. Both terminals of a two-terminal sensor connect to the differential amplifier input, and shielding and guarding circuits typically connect to signal ground and special guard-shield terminals.
Unattended ground sensor systems are used to electronically detect the presence of personnel and vehicles and to monitor their movements. Sensor systems detect motion, sound, heat, and ferrous metal. When activated by an intrusion, sensors transmit a coded radio frequency message to a portable or base monitoring
What is a Tactical Unattended Ground Sensor T-UGS?
Tactical unattended ground sensor T-UGS are small ground-based sensors that collect intelligence through seismic, acoustic, radiological nuclear and electro-optic means. These sensors are networked devices that provide an early warning system to supplement a platoon size element and are capable of remote operation.
Who are the manufacturers of ground based sensors?
The current generation is manufactured by Textron Defense Systems a subcontractor under Boeing . T-UGS are small ground-based sensors that collect intelligence through seismic, acoustic, radiological nuclear and electro-optic means.
Are there any unattended ground sensor systems in the Marine Corps?
The Hotline allegation of Marine Corps mismanagement of the ‘rRSS development was valid. Also, program duplication existed between the I-REMBASS and TRSS, and Marine Corps TRSS procurement funds were fncorrectly used to fund research and development tasks.
