IPS - Indoor Navigation Positioning System DSP Starter Set NIA v5.07
Features
Content
- 4 x DSP Beacons v5.07 915MHz as stationary beacons
- 1 x Beacon HW v4.9 with IMU 915 MHz as mobile beacon
- 1 x Modem HW v4.9 915MHz
Distance between beacons
- Reach up to 50 meters in lab conditions
- Recommended distance is 30 meters (Transducer of Beacon HW v4.9 looking straight at Beacon DSP HW v5.xx)
- 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
- Reach 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)
- 0.05–25Hz. With IMU fusion enabled – 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
- tationary beacon with 1Hz update rate => 1 week
- Future power saving features may increase battery life to 1year and more
- microUSB – recommended for permanent use
Weight
- 25g (board + battery + plastic housing)
- 9g (board only)
Size
- 47x42x15mm
Documentation and Support
Marvelmind Indoor Navigation System is an off-the-shelf indoor navigation system designed to provide precise (±2cm) location data to autonomous robots vehicles (AGV), drones and forklifts. It can also be used to track other objects that the mobile beacon is installed upon, for example, virtual reality (VR) systems, helmets for construction workers or miners, jackets, etc.
The Additional DSP Beacon for IPS - Indoor Navigation Positioning System DSP Starter Set NIA v5.07 is an integral part of indoor GPS navigation system. Marvelmind Indoor Navigation System is an off-the-shelf indoor navigation system designed to provide precise (±2cm) location data to autonomous robots, vehicles (AGV), drones and forklifts. It can also be used to track other objects that the mobile beacon is installed upon, for example, virtual reality (VR) systems, helmets for construction workers or miners, jackets, etc.
The navigation system is based on stationary ultrasonic beacons that are united by radio interface in a license-free band (915MHz). The location of the mobile beacon is calculated based on the propagation delay of an ultrasonic signal (Time-Of-Flight or TOF) to a set of stationary ultrasonic beacons using trilateration.

DSP beacons can work in Non-Inverse and in Inverse Architectures. Read more about the architectures.
This Starter Set is for Non-Inverse Architecture
Key requirements for the system to function properly:
- For 3D (X, Y, Z) tracking – An unobstructed line of hearing/sight by a mobile beacon to three or more stationary beacons simultaneously
- For 2D (X, Y) tracking – An unobstructed line of hearing/sight by a mobile beacon to two or more stationary beacons simultaneously
- Distance to the nearest 2 or 3 beacons – not more than 30 meters (recommended). In ideal conditions – up to 50 meters
The DSP beacon HW 5.xx differs from regular Beacon HW v4.9 in several ways:
- It 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 DSP v5.xx than between Beacon HW v4.9 and Beacon HW v4.9
- DSP 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 working ultrasonic frequency of Beacon HW v4.9 is HW-defined by ultrasonic sensors and can’t be changed
- DSP beacon can receive several ultrasonic frequencies at once. That is used in Inverse Architecture. See the comparison
- The DSP Beacon is signficantly smaller, than Beacon HW v4.9
- The DSP 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
