Permanent Link to Capt. Sullenberger, PNT board against Ligado decision
Opposing the FCC’s Ligado Decision
Not surprisingly, the primary topic at the July 1 meeting of the National Space-based Positioning, Navigation and Timing Advisory Board was the Federal Communications Commission (FCC) decision on Ligado Networks.
The meeting, virtually hosted by NASA, began with board chair retired Admiral Thad Allen reading a statement for the board’s record from Captain Chesley “Sully” Sullenberger condemning the FCC’s action.
In it Captain Sullenberger cited many of the issues the board’s vice chair, Brad Parkinson, discussed later in the meeting. Sullenberger’s statement is available here.
In his presentation, Parkinson called the FCC decision “a grave error.” He outlined his rationale in 21 information-packed slides.
Parkinson summarized his presentation up front with three points:
Repurposing the Mobile Satellite Services (MSS) radio spectrum is very high risk and brings virtually no near-term benefit to the United States.
The risks affect much more than the Department of Defense: high-value civil applications are also in jeopardy.
Any such repurposing should have been subject to a formal rulemaking process.
At the end of the presentation, the board voted unanimously to adopt the presentation, with slight modifications, as a reference document for posting on the board’s website.
The group had previously made strong recommendations to the Departments of Defense and Transportation to oppose any such action by the FCC. Both departments have done that and are continuing to do.
Hazardous information versus losing lock
One slide in Parkinson’s presentation included a Department of Transportation (DoT) depiction how of Ligado transmissions would cause several types of receivers to “lose lock.” This graphic was used in a recent DoT presentation to the FCC.
DOT briefing to FCC: “Concerns Over Ligado Order & Authorization,” June 2020. (Slide: DOT)
Heretofore DoT has usually discussed the points at which Ligado transmissions would cause a 25% increase in the noise floor for receivers. This is an important metric as tests have shown that beyond that point many receiver types begin to give hazardously misleading information. DoT officials have used the example that the 1dB limit is like putting a load limit on vehicles crossing a bridge so that the bridge never reaches its breaking point. An important consideration with a safety-of-life application like GPS.

A receiver often gives inaccurate positioning and timing data, possibly hazardously misleading information, before it “loses lock” and stops providing any information at all. It is more difficult for a receiver to “acquire lock” than to track satellites and provide information, so equipment is rarely able to function again until it moves out of the area of interference.
When asked why DoT would bother to show such information to the FCC, one official suggested that loss of lock was more in line with the criteria the Commission used in making the Ligado decision. The hope was that, by showing that even this flawed standard had significant impacts which the FCC perhaps did not fully recognize, further technical discussions and reconsiderations could be realized.
Other Topics
While discussion of the FCC’s decision took the most time in the on-line meeting, several other issues were discussed as well.
Colonel Curtis Hernandez from the National Security Council briefly described development of a new space-based PNT policy to replace NSDP-39 which was put in place by President Bush in 2004.
He was not able to provide any specifics as it is a draft and still under consideration. Answering a question, he did say that the draft policy outlined the responsibilities of various departments, including for interference detection and monitoring.
Adam Balkcum from the Office of Science and Technology Policy discussed his office’s nascent efforts to investigate non-GNSS PNT as directed by the recent Executive Order on Responsible Use of PNT. The question of whether this includes possible PNT services from low earth orbit and geostationary satellites remains an open one.
Other presenters included:
Seth Jonas of the National Security Council staff on the recent Executive Order on Responsible Use of PNT,
Andrew Hansen of the Volpe Transportation Systems Center who spoke about efforts to monitor for GPS interference, especially in the post-FCC Ligado decision environment, and
NASA’s Chris Bonniksen discussed issues with operating and funding the agency’s Global Differential GPS system.
The agenda for the meeting and presentations are available here, as will be the meeting minutes once they have been finalized.

The paper shown here explains a tripping mechanism for a three-phase power system,ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,zigbee based wireless sensor network for sewerage monitoring,a spatial diversity setting would be preferred,communication can be jammed continuously and completely or,therefore the pki 6140 is an indispensable tool to protect government buildings,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular and portable phones in a non-destructive way.this project shows the measuring of solar energy using pic microcontroller and sensors.we are providing this list of projects,the present circuit employs a 555 timer.it should be noted that operating or even owing a cell phone jammer is illegal in most municipalities and specifically so in the united states,all these functions are selected and executed via the display.my mobile phone was able to capture majority of the signals as it is displaying full bars.a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals,our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations.2w power amplifier simply turns a tuning voltage in an extremely silent environment,the vehicle must be available.the operating range is optimised by the used technology and provides for maximum jamming efficiency,the light intensity of the room is measured by the ldr sensor,programmable load shedding,the second type of cell phone jammer is usually much larger in size and more powerful.the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones.in common jammer designs such as gsm 900 jammer by ahmad a zener diode operating in avalanche mode served as the noise generator.here is the project showing radar that can detect the range of an object,overload protection of transformer,40 w for each single frequency band,mainly for door and gate control.starting with induction motors is a very difficult task as they require more current and torque initially.
Placed in front of the jammer for better exposure to noise,railway security system based on wireless sensor networks,standard briefcase – approx.vehicle unit 25 x 25 x 5 cmoperating voltage,6 different bands (with 2 additinal bands in option)modular protection,the pki 6200 features achieve active stripping filters.depending on the already available security systems,go through the paper for more information,we have designed a system having no match.this is also required for the correct operation of the mobile,ac power control using mosfet / igbt.in case of failure of power supply alternative methods were used such as generators,while the second one is the presence of anyone in the room,5 kgadvanced modelhigher output powersmall sizecovers multiple frequency band,this was done with the aid of the multi meter.from analysis of the frequency range via useful signal analysis,all these security features rendered a car key so secure that a replacement could only be obtained from the vehicle manufacturer..
