1.1
INTRODUCTION
PURPOSE
This document is in response to CCSDS A02.1-Y-2, “Restructured Organization and Processes
for the Consultative Committee for Space Data Systems” [2], which for elevating a book to Blue
status (adopted recommended standard) requires that “At least two independent and
interoperable prototypes or implementations must have been developed and demonstrated in an
operationally-relevant environment, either real or simulated”.
The document under adoption is CCSDS 131.3-R-1, “CCSDS Space Link Protocols over ETSI
DVB-S2 standard” [1].
Document CCSDS A02.1-Y-2 [2] also requires that “If patented or otherwise controlled
technology is required for the separate implementations, they each must also have resulted from
separate exercise of the licensing process”. This requirement is also addressed in the present
document.
1.2
SCOPE
This document is not a part of any CCSDS Recommended Standard.
1.3
ORGANIZATION OF THIS REPORT
This document is divided into three parts. Section 1 (this section) presents the purpose and
organization of the book. Section 2 documents several independent implementations and
simulations of the proposed standard. Section 3 documents licensing agreements for the
proposed standard.

2.1
INDEPENDENT VALIDATIONS OF THE STANDARD
OVERVIEW
The proposed standard “CCSDS Space Link Protocols over ETSI DVB-S2 standard” is an
adaptation profile describing how to use the ETSI DVB-S2 standard [3] to transmit CCSDS
Transfer Frames for telemetry purpose. The interface between CCSDS and DVB-S2 is based on
ASM and CADU already introduced in [5] and widely used in the CCSDS community.
Consequently, the considered validation is limited to DVB-S2 modulation and coding.
A number of implementations (software and hardware, on-board and on-ground…) are listed in
the following sections.
2.2
SOFTWARE IMPLEMENTATIONS
The DVB-S2 is an already widely used satellite communication standard. Many DVB-S2
performance analyses, on AWGN channel or on satellite communication channel, are
consequently available in technical literature.
Concerning performances on AWGN channel, some performances are given in [4] (pages 67 and
68). Missing MODCOD have been simulated by CNES in [6].
Concerning performances in a representative context, the satellite communication channel is
very similar to the telemetry channel, and DVB-S2 telecom transmissions prove the feasibility of
a DVB-S2 telemetry transmission. ESA simulations dedicated to the telecom context are
presented in [7]. Similar simulations can also be found in [8].
Further results dedicated to DVB-S2 telemetry are presented in [9].
2.3
TRANSMITTER IMPLEMENTATIONS
Many DVB-S2 telecom transmitters are available, currently with maximum data rates from 30 to
50 MBauds.
CNES intends to use DVB-S2 for its LEO satellite high data rate telemetry from 2020 and
beyond. An Elegant Bread Board of a telemetry transmitter at 150 MBauds will be delivered to
CNES in 2015.
A transmitter using DVB-S2 at data rates above 3 GBauds has been experimented by NASA in
[12].
2.4
RECEIVER IMPLEMENTATIONS
Many DVB-S2 telecom receivers are available, with data rates up to 30 to 50 MBauds. Some of
them includes the VCM/ACM capability. The use of these receivers can be considered for low
data rate telemetry.

VALIDATION OF THE ETSI DVB-S2 STANDARD FOR USE WITH CCSDS SPACE LINK
PROTOCOLS
Zodiac Data System (ZDS) has implemented on its Cortex HDR XXL receiver all the DVB-S2
MODCOD, with modulation from QPSK to 32-APSK, and with short and normal frames, as
described in [13]. A test transmitter has been included in the Cortex as well. Data rates of 250 to
300 MBauds are achievable (for all modulations). This equipment also includes the VCM/ACM
capability.
2.5
INTEROPERABILITY TESTING
Interoperability and performances of telecom equipments from 7 manufacturers was evaluated in
[10].
The interoperability of equipments from 6 manufacturers was also verified by CNES in [11]
(telecom equipments from 4 manufacturers, one measurement equipment, and the Zodiac Data
System Cortex HDR XXL telemetry receiver).
The interoperability was found to be very good in both evaluations.

PATENTS FOR THE PROPOSED STANDARD
The CCSDS draws attention to the fact that compliance with [1] may involve the use of patents.

obtained from:
