Description[edit]

The Norsec Wireless Power Transmitter is an uni-directional, A-to B, far field microwave electical transmission system. The rotatable base transmitter delivers a narrow, non-lethal Microwave beam to a dedicated base receiver.

The transmitter must be aligned to the base station in order to transmit any power. The brightness of the transmitter's collimator arc provides an indication of transmission intensity. Note that there is an attrition over longer ranges, so the unit requrires more power over greater distances to deliver the same output.


General behaviour[edit]

  • 5kW is the maximum PowerPotential that can be transmitted, this amount is reduced by distance.
  • Unaffected by storms.
  • Using two emitters on the same reciever doesn't appear to work
  • A Logic Transmitter can mirror recievers, but not emitters.
  • The coordinates of these devices will change slightly when the head moves.
  • Both structures and terrain will block the beam. Once a beam is formed it will no longer be blocked by building things between them.
  • When these devices are built their placement rotation is important. The easiest way is to point the data-port to the north (0° on the space suit compass), otherwise a horizontal correction angle must be added or subtracted when doing the math.
  • When the device head is being rotated horizontally it is rotating in the opposite of the expected direction, this must be compensated for when doing the math.


Range[edit]

Power transfer with 4000 W PowerPotential[edit]

98m = 3630 W (-0.37kW)
198m = 2863 W (-1.14kW)
300m = 1409 W (-2.59kW)
400m = 0 W


Power transfer with 5000 W PowerPotential[edit]

98m = 4630 W (-0.37kW)
198m = 3863 W (-1.14kW)
300m = 2409 W (-2.59kW)
400m = 651 W (-4.35kW)


Alignment formulas[edit]

All dataports points north, the delta values are calculated from: "reciever coordinate" - "emitter coordinate"

Horizontal for "emitter" = atan2( delta-x / delta-z ) * 180 / pi
Vertical for "emitter" = 90 + atan( delta-y / sqrt( (delta-z)^2 + (delta-x)^2 ) ) * 180 / pi

Horizontal for "reciever" = 180 + Horizontal for "emitter"
Vertical for "reciever" = 180 - Vertical for "emitter"

Comments:
When the data-port points north, +0° is added to the Horizontal rotation.
When the Vertical rotation is 90° the device head points towards the horizon, 90° must be added because when delta-y is 0 (no height difference) then atan() will be 0
Both atan2() and atan() uses radians for the angle, radians are converted to degrees by multiplying with 180 / pi
atan2(x/z) should be z/x in a normal situation, but it has been inverted to compensate for the devices inverted rotation direction
atan(y/x) uses Pythagoras theorem to set x as the horizontal-plane distance between emitter and reciever
