Description

The Super-Beacon-Outdoor is an outdoor version of the Super-Beacon. See detailed specifications for the Super-Beacon-Outdoor.

All essential SW, as well as Marvelmind Dashboard API, are already included in the price of the beacon. Just download the Marvelmind SW pack: https://marvelmind.com/download/ => https://marvelmind.com/pics/marvelmind_SW.zip.

Example of usage of Super-Beacon-Outdoor

Read more about Super-Beacons-Outdoor usage on the example of boats: Autonomous boats without GPS.

The Super-Beacon-Outdoor survives complete submersion into water. See the demo: https://www.youtube.com/watch?v=cIA2Gc5KaQI. However, as with any outdoor version, the performance during the rain and dust exposure is not guaranteed and depends on the severity of the conditions. It is also highly recommended to use external umbrellas or shields and similar protection, as well as periodic cleaning from dust to minimize the effect of long-term exposure to adverse environmental conditions.

The Super-Beacon has compound-sealed electronics, and its sensors are protected with a special IP56-rated protective membrane. Membranes bring additional minor losses to ultrasound signals. Thus, theoretically speaking, the range of the Super-Beacon-Outdoor is slightly lower than that of a regular Super-Beacon. However, in the majority of cases, the difference is not noticeable.

The Super-Beacon-Outdoor is a dual-use beacon – it can both receive and transmit ultrasonic pulses.

The Super-Beacon-Outdoor can be used in the Non-Inverse Architecture (NIA), the Inverse Architecture (IA), and the Multi-Frequency Non-Inverse Architecture (MF NIA): Architecture comparison.

The beacon Supports a license-free 915MHz ISM band (for example, US, Japan, Korea) and license-free SRD band 868MHz (for example, EU, Russia). Support of the 433MHz ISM band (EU, Russia) comes with a larger order. Notice that, for example, the 915MHz is the band’s name. The supported frequencies are from about 860MHz to 930MHz.

All Super-Beacons have 6D IMU (3D gyro + 3D accelerometer) onboard.

Distance between beacons

  • Reaches up to 50 meters in lab conditions
  • Recommended distance is up to 30 meters (RX4 to RX4)
  • Range of stable tracking of Super-Beacon-Outdoor + Super-Beacon-Outdoor 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 Super-Beacon-Outdoor

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 directly 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 1000mAh
  • Battery lifetime totally depends on usage
  • Receiving beacon mode with 8Hz update rate and 10m-submaps => up to 30h
  • Transmitting beacon with 1/10Hz update rate => several months
  • 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

  • 75 grams (including 1000mAh battery, housing and 50-mm antenna)

Size

55x55x33 mm (with 50mm antenna: 55x55x65mm)

Frequencies of 19kHz, 25kHz, 31kHz, 37kHz, 45kHz, which is the recommended frequency for noisy construction site ?

If you are using an IA system or MF NIA, then you would need all of them or most of them for real maps. See more about NIA vs. IA vs. MF NIA: https://marvelmind.com/pics/architectures_comparison.pdf.

If you are using NIA, then only one frequency is enough. And your question is very good and very valid. Short description:
– 19kHz – strong signal, but close to audible band – not recommended for noisy sites
– 25kHz – very strong signal – recommended when you need very large distances: https://youtu.be/OYrLOpGvbig
– 31kHz – strong signal – safe choice, when you are unsure. Strong signal and already far from the audible noise, i.e. relatively weakened noise
37kHz – strong signal and even more weakened external noise – perhaps the most recommended for the noisy sites – your case
– 45kHz – weak signal, but the weakest external noise as well. So overall signal/noise ratio can be very good actually
