Description
- Marvelmind Super-Beacon-Outdoor (31kHz)
- Offers an outdoor version of the Super-Beacon
- Dual-use beacon: Receive and Transmit ultrasonic pulses
- Protected with special IP56-rated protective membrane
- Works with regular Beacons HW v4.9, Mini-RX and Industrial-RX
- Supports full submersion into water
The Marvelmind Super-Beacon-Outdoor (31kHz) is an outdoor version of the Super-Beacon. Performance during the rain and dust exposure is not guaranteed and depends on the severity of the conditions. As well, it is highly recommended to use external umbrellas 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 the ultrasound signal.
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 in the Multi-Frequency Non-Inverse Architecture (MF NIA).
The Super-Beacon-Outdoor can receive any ultrasonic frequency from the bands: 19 kHz, 25 kHz, 31 kHz, 37 kHz, 45 kHz. The filter can be simply selected in the Dashboard. It has a separate receiving part with a single wide-beam microphone and sharp DSP filters (like Mini-RX or Industrial-RX has).
Thus, it is more sensitive, than Beacon HW v4.9, more resistant to external noise. It is easier to set up because you don’t have to care about turning on and off ultrasonic sensors in order to optimize coverage vs. sensitivity
- 1 x Marvelmind Super-Beacon-Outdoor (31kHz)
- 55x55x33mm (55x55x65mm with 50mm antenna)
Distance between beacons
- Reaches up to 50m 1D / Up to 120m 1D (With Marvelmind Horn)
- Range of stable tracking of Super-Beacon + Super-Beacon 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
Additional sensors
- IMU - Accelerometer + gyroscope
Interfaces
- UART
- SPI
- Virtual UART via USB
- NMEA
Location update rate
Non-Inverse Architecture
- 0.05–25 Hz
- 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, the update rate of 25Hz for 1 mobile beacon will result in update rate of 25 Hz/2 for 2 mobile beacons, and 25 Hz/3 – for 3 mobile beacons, etc. – TDMA approach
- Depends on the radio interface profile (500 kbps vs. 38 kbps)
Inverse Architecture
- 0.05 – 25 Hz. Future SW releases are planned to support IMU fusion that will enable the update rate of up to 100 Hz
- 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 (500 kbps vs. 38 kbps)
Power supply and battery lifetime
Internal
- Li-Ion battery 1000 mAh (soldered o the board)
- Battery lifetime totally depends on usage
- Receiving beacon mode with 8 Hz update rate and 10 m-submaps => up to 30 h
- Transmitting beacon with 1/10 Hz update rate => several months
- Future power saving features may increase battery life to 1 year and more (with very slow update rate or location update on
- demand)
External
- MicroUSB – recommended for permanent use
Weight
- 79 grams
Supported Accessories
- Antenna Full-Size
- Horn
