Defender Lance
Defender Lance
Experience the performance you never thought possible with the Defender Lance automated direction-finding system. Leveraging the power of Transformational Security’s new phase-coherent, n-channel Atom Defender n-IQ receiver, Defender Lance can determine lines of bearing with lightning speed and accuracy.
Embedded Omnidirectional Antenna
Spectrum monitoring, surveillance, and signals analysis up to 43 GHz with the embedded modified biconical antenna and Atom Defender n-IQ.
From Line of Bearing to Position Location
Multiple DFS installations can work together and with existing IPMS infrastructure to interpret the intersection of LOBs to generate 95% confidence interval position estimation areas.
Typical Accuracy Better than ±2 Degrees
LOB accuracy is frequency dependent. Increased averaging can increase accuracy. Mean error across all frequencies in simulations is nearly zero.
