Description

The Mini-RX Beacon can be used in both the Non-Inverse Architecture (NIA) and the Inverse Architecture (IA):

The is a 915MHz version only (for the moment).

All Mini-RX beacons have 6D IMU (3D gyro + 3D accelerometer) onboard.

The Mini-RX beacon differs from regular Beacon HW v4.9 in several ways:

  • The Mini-RX is an RX-only beacon, i.e. it can receive, but it cannot transmit ultrasonic signal
  • The fact that it is RX-only makes it far more sensitive, i.e. you will get a longer range between Beacon HW v4.9 and the Mini-RX than between Beacon HW v4.9 and Beacon HW v4.9
  • The Mini-RX beacon can receive any ultrasonic frequency from the bands: 19kHz, 25kHz, 31kHz, 37kHz, 45kHz, 56kHz. The filter can be simply selected in the Dashboard. At the same time, the ultrasonic frequency of Beacon HW v4.9 is HW-defined by ultrasonic sensors and can’t be changed
  • The Mini-RX beacon can receive several ultrasonic frequencies at once. That is used in Inverse Architecture. See the comparison
  • The Mini-RX Beacon is significantly smaller, than Beacon HW v4.9 in volume and weight. See the Beacons Comparison table
  • The Mini-RX Beacon can work with regular Beacons HW v4.9 in any combination as a part of a Starter Set or as a part of navigation systems and it is a superior RX-only replacement to HW v4.9. At the same time, since it is RX-only beacon, the Beacons HW v4.9 are here to stay as universal dual-use beacons. In all cases, beacons shall use the same radio band

Distance between beacons

  • Reaches up to 50 meters in lab conditions – signal strength limited. Practical limitation is 25m now – memory limited and may be fixed in upcoming SW releases
  • Recommended distance is up to 30 meters (Transducer4 of Beacon HW v4.9 looking straight at Beacon DSP HW v5.xx) – signal strength limited. But see the memory limitation above
  • Range of stable tracking of DSP beacon + Beacon HW v4.9 is 20-50% bigger, than the range of Beacon HW v4.9 + Beacon HW v4.9 in the same conditions

Coverage area

  • Reaches up to 1000 m2 with the Starter Set configurations
  • Coverage for larger territories is similar to cellular networks

Location precision

  • Absolute: 1–3% of the distance to the beacons
  • Differential precision: ±2 cm
  • Differential precision is on par or better than in the Beacon HW v4.9, partially, because the sensor is a point – not as spread sensors of HW v4.9; and, partially, because of higher processing power and more advanced algorithms of the DSP beacon

Location update rate

Non-Inverse Architecture:

  • 0.05–25Hz
  • Can be set manually or in automatic mode
  • Depends on the distance between the mobile and stationary beacons (shorter distance — higher update rate)
  • Depends on the number of mobile beacons: for example, update rate of 25Hz for 1 mobile beacon will result in update rate of 25Hz/2 for 2 mobile beacons, and 25Hz/3 – for 3 mobile beacons, etc. – TDMA approach
  • Depends on the radio interface profile (500kbps vs. 38kbps)

 

Inverse Architecture:

  • 0.05–25Hz. Future SW releases are planned to support IMU fusion that will  enabled update rate of up to 100Hz
  • Can be set manually or in automatic mode
  • Depends on the distance between the mobile and stationary beacons (shorter distance — higher update rate)
  • Doesn’t depend on the number of mobile beacons – all of them are receiving
  • Depends on the radio interface profile (500kbps vs. 38kbps)

Power supply and battery lifetime

Internal:

  • LiPol battery 750mAh
  • Battery lifetime totally depends on usage
  • Stationary beacon with 8Hz update rate => up to 30h
  • Stationary beacon with 1Hz update rate => 1 week
  • Future power saving features may increase battery life to 1year and more (with very slow update rate or location update on demand)

External:

  • microUSB – recommended for permanent use

Weight

  • 25g (board + battery + plastic housing)
  • 9g (board only)

Size

47x42x15mm
