Synchronization: The acquisition and maintenance of system time. The SYNCHRONIZING terminal must correct the ERROR (Initial Clock Offset) between terminals (ε).

RTT Messages: represent the only exception to the rule that a terminal can transmit or receive, but not both, in a given time slot.

In Link 16 operations, each terminal estimates how well it knows system time. This estimate is based on: 1. Clock drift, 2. Accuracy that terminals replying RTT interrogations know system

time, 3. The time since it last completed an RTT exchange.

The terminal uses this information to set its Time Quality (TQ). By definition,

Only the Network Time Reference (NTR) has a TQ = 15


MIDS-LVT & LINK-16: MIDS-LVT & LINK-16: An IntroductionAn Introduction Link 16 Overview:Link 16 Overview: Round Trip Timing (RTT)Round Trip Timing (RTT)

User Terminal: Transmit an RTT Interrogation (RTTI) in the beginning of the slot and

receive an RTT Reply (RTTR) later in the slot. Net Time Reference (NTR):

Receive an RTTI in the beginning of the slot and transmit an RTTR later in the slot.


MIDS-LVT & LINK-16: MIDS-LVT & LINK-16: An IntroductionAn Introduction Link 16 Overview:Link 16 Overview: Relative NavigationRelative Navigation

Determining the distance of JUs by measuring the Time of Arrival (TOA) of received PPLI and correlating that information with reported LAT/LONG

Synchronous nature of Link 16 provides the basis for individual JU’s to determine own-unit location relative to other JU’s in the network.

An automatic function of the terminal


MIDS-LVT & LINK-16: MIDS-LVT & LINK-16: An IntroductionAn Introduction Link 16 Overview:Link 16 Overview: Relative NavigationRelative Navigation

The Terminal's navigation function performs all computations necessary to determine own unit navigation data using:

1. TOA measured on:• received Link 16 PPLI• data contained in the messages

2. Inputs from:• INS (Inertial Navigation Systems) • GPS (Global Positioning Systems) • other host navigation and altitude systems

3. Network time from the Terminal's clock.

Functional exchange: A data exchange characterized by a functional message and the rules to exchange it. Defined by: Functional Input Messages (FIMs),

Example: FIM10 Host Navigation Data Type 1 FIM Functional Output Messages (FOMs),

Example: FOM03 Ongoing BIT & Status FOM Associated application-level protocols.

A physical exchange is a data exchange characterized by a physical message and the rules to exchange it. It is defined by Bus Input Messages (BIMs), Bus Output Messages (BOMs), and associated bus-level protocols.
