Marvelmind DSP 2D Lite Indoor Navigation Positioning System (Inverse Architecture)

• 1 x DSP RX Beacons 915/868MHz as mobile beacons (Beacon Mini RX)
• 2 x Stationary Beacon TX with IMU 915/868 MHz as stationary beacons
• 1 x Modem HW v4.9 915/868 MHz

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

Inverse Architecture:

• 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:

• LiPo 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

External:

• microUSB – recommended for permanent use

Weight

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