The MOU between OMG and INCOSE formalizes the working relationship between the two parties as they develop and distribute the INCOSE cubesat reference model (CRM) to advance standards for cubesats.

A 1U cubesat is 10x10x10 centimeters with a mass of about 1.3 kilograms. CubeSat units can be joined to form a larger satellite such as 2U, 3U and 6U. Their small payload makes standalone launch cost-prohibitive but allows cubesats to join launches from other organizations at a significantly reduced cost. The nanosatellite and cubesat database reports that cubesat launches tripled from 2016 to 2017 to nearly 300 launches. The number of cubesats and the number of organizations developing cubesats have increased dramatically.Beam hopping however, there is no common reference model to design a cubesat, thereby limiting interoperability, slowing development times and forcing constant research to remain current on the latest innovations.

The CRM provides the logical architecture of a cubesat space and ground system. The CRM logical components are intended to be used as a starting point for a mission-specific cubesat logical architecture, followed by the physical architecture and the cubesat development. The CRM is also sufficiently flexible to accommodate different logical architectures.

William hoffman, president and COO of OMG and garry roedler, president of INCOSE, signed the MOU.Beam hopping under the terms, the INCOSE CRM will go through the OMG standardization process. In addition, OMG will issue a request for proposals regarding the cubesat reference model.

Hoffman added that both OMG and INCOSE share a mutual commitment to support and accelerate knowledge growth in the systems engineering arena. Developed by INCOSE using the OMG systems modeling language™ (sysml®), the CRM is already in a model form, providing a fill-in-the-package framework and identifies subsystems to consider and other agencies to coordinate prior to launch. Space-mission-procuring organizations will use the CRM to capture mission requirements in a standard format that is readily accessible and understandable by vendors and developers.”

Garry roedler,noted that this announcement reinforces the joint cooperation with OMG to deliver a cubesat reference model that applies a model-based systems engineering (MBSE) method and will be reusable and extensible to a variety of specific space missions and payloads.

The new modem’s single carrier and beam hopping architecture enables substantially higher throughput from wideband (500 mhz) satellite transponders to enable superior connectivity. With satixfy’s modem, through single 500 mhz carrier and beam hopping capability, satellite operators and service providers will be able to get significantly higher throughput for applications requiring it, such as trunking, enterprise, and backhauling.CubeSat reference model A 1U rack mount enterprise model is available today and a consumer unit will be available in Q4 2018.

The wideband SDR modem demonstration using the R&S®SMW200A vector signal generator from rohde & schwarz shows no errors at -2 db SNR with DVB-S2 QPSK rate ¼. The R&S®SMW200A single-instrument solution simplifies the testing of components, modem devices and satellite payloads. The vector signal generator supports DVB-S2/DVB-S2X and the latest satellite standard of a mega constellation. It is the first fully calibrated wideband solution with an RF modulation bandwidth of 2 ghz on the market and generates signals across all frequencies and satellite bands up to 40 ghz in the ka-band.CubeSat reference model

Another demonstration is based on teamcast TYGER, a wideband, DVB-S2/S2X compliant modulator offering high rates (up to 480 mbaud, i.E., up to 2 gbps), time slicing (annex M), CID management and GSE IP encapsulation for maximizing, payload, operational flexibility, and return on investment. For IP transport, the use of the GSE adaptation algorithm insures lower overhead and maximized capacity and spectrum efficiency. By meeting the requirements of the DVB “annex M,” TYGER enables the mixing of services (broadcast and broadband) over the same satellite carrier. Specifically, it supports time-slicing, a process to split a wideband signal — up to 2 gbps — into a number of independent low rates services, to keep the receiver IC complexity and price low, which is a mandatory requirement for a mass market adoption.Beam hopping

At satellite 2018, satixfy will also be demonstrating its beam hopping emulator. The company, alongside its partners, is leading the industry in developing and setting standardization efforts for super-frame structure and beam hopping waveforms in DVB, and resource management, as well as beam hopping illumination plan algorithms and configurations in ETSI.

Yoel gat, the satixfy CEO, said that the company is pleased to introduce their first wideband modem and demonstrate the unbeatable performance of the SX-3000 chip in terms of QEF performance with a fraction of db from DVB-S2X guidelines with over 2 gbps throughput per 500 mhz transponder. The satixfy team is the first in reaching industry leading benchmarks that, until now, were out of the industry’s grasps.CubeSat reference this modem demonstrates the company’s advantages over the competition. It is the only one in the market that supports beam hopping and VLSNR and is the only soc that supports the demodulator, modulator, dual core host CPU and 3 dsps, with periphery of three 1 GB ethernet ports, UART and many peripheral interfaces," said .

TeamCast is also introducing a totally disruptive solution for optimizing satellite links — the solution uses a feedback channel through a regular low bitrate internet connection to optimize the link budget, and increase the available payload capacity while keeping your costs low.

The feedback information elaborated by the downlink neptune receiver is used by the uplink vyper modulator to pre-correct the linear and non-linear impairments of the on-board transponder chain. The optimization is automatic and transparent for the user. It can be used while the link actually carries user data, without any need to put the transmission on hold. No specific knowledge of the transponder characteristic is necessary; no specific skills are required for the operator.Linear power the link budget automatically increases while the link is used. That means the link margin is getting better providing the possibility either to secure the link against unexpected adverse conditions or increase the useful bandwidth by adjusting the modulation parameters.

SmartGate, a DVB-S2/S2X satellite modulator that embeds an advanced powerful filtering and routing process as well as a layer 2 and 3 optimized encapsulation with full management of PSI/SI tables, is another teamcast new offering. SmartGate is a real IP and ethernet gateway with ultra-low latency for satellite access. It also offers an optimal bandwidth management and an NCR process to provide frequency synchronization to remote devices.Linear power
