RC-Cam Encyclopedia

Recommended Posts

This thread is the RC-Cam Encyclopedia:

Please join in, and explain in short the cryptic shorts that we all use.

I will start with a few:

HMD = Head Mounted Display

another name for VR googles, Virtual Reality screen(s)

FPV = First Person View, is Flying the plane after video feed.

RPV = Remote Person View

UAV = Unmanned Aerial Vehicle. A powered aerial vehicle sustained in flight by aerodynamic lift and guided without an onboard crew. It may be expendable or recoverable, and can fly autonomously or be piloted remotely. There are two categories of UAVs: drones and RPVs.

UCAV = Unmanned Combat Air Vehicle

NMEA = the serial data string system that come out from a GPS receiver unit.

GPS = Global Position System, often small receivers are called GPS modules.

RSSI = Receive Signal Strength Indicatior, often an analog signal from a receiver

that tell how strong the input signal is.

R/C or RC = Radio Control, can be any frequency like 35, 40, 72 and so on,

often used to move the servos in a model plane or such.

CCD = Charge Coupled Device: one of the two main types of image sensors used in digital cameras. CCD is often better than CMOS and also more expensive.

CMOS = Complementary Metal-Oxide Semiconductor: one of the two main types of image sensors. Its basic function is the same as that of a CCD. only CMOS sensors are cheaper and lower quality.

LED = Light-Emitting Diode: diode such that light emitted at a p-n junction is proportional to the bias current; color depends on the material used

NMEA - The ASCII data stream received from navigation equipment (such as GPS receivers) conforming to the NMEA 0182 Version 2.0 specification, details at these sites:

AVS - Aerial Video System (ie: video feed to the ground usually, and all electronics involved)

LED - Light Emitting Diode, a semiconductor that generates photons from voltage passed to it.

GPS - Global Positioning System/Satellite. 24 satellite orbit earth, providing 6 satellites of coverage to every point on earth for relatively accurate position information

RSSI - Received Signal Strength Indicator, how strong the single that was recieved is. Usually 0-5v, 0v being bloody awesome, and 5v being darn poor.

PCB - Printed Circuit Board

CCD - Charge-Coupled Device, converts light into an electrical current. These make the best quality cameras currently availiable.

TX = Transmitter

RX = Receiver

A/V = Audio – Video

MHz = Mega Hertz. A measurement of radio frequency.

Ghz = Giga Hertz. A measurement in radio frequency. Commonly used by us on our A/V TX-RX, radio TX-RX

mW = milli-Watt. A measurement of power consumption.

Omnidirectional Antenna (rubber ducky antenna) = A antenna system which radiates power uniformly in one plane with a directive pattern shape in a perpendicular plane.

From above: mW = milli-Watt. A measurement of power consumption.

Also a measure of power output from transmitters, and power output from small audio amplifiers or preamplifiers as measured across a specific load or impedance.

And for the old timers,

Mc = megacycle or as commonly known Mega Hertz

Gc = Gigacycle.............as above...........Giga Hertz
