    Mr Mousley asks the analyst about data received from Facebook in the United States. He asks if the data gives any more details than what the police already had. She replies, "No".

    He asks if in some cases, the data provided was less than what the police already had. She replies: "In some instances, yes".

    The court hears how cloud data from Nicholson's phone shows he received an email from Facebook on July 25, at 7.29am, saying that he had received a message from Lucy McHugh.

    Cloud data shows Nicholson logged on to Facebook around 8.52am and used messenger. Lucy McHugh's data shows she logged in to her Facebook account at the same time.

    The court is told about data showing a delivery of trainers to Nicholson's friend's address on July 25. The delivery is signed for.

    Other data shows how Youtube videos involving animals were being watched via Nicholson's phone during the period when Lucy is seen walking on CCTV walking towards the Sports Centre. One is titled 'Animals react to fidget spinners'.

    The court hears how Nicholson's phone data shows no step count data between around 9am and 10.50am. The data then shows Nicholson respond to a text from a friend, who had showed concern after hearing that he was ill.

    Between 11am and 12.19am, the court hears how data on Nicholson's phone shows a number of outgoing voice calls made, including two to Lucy's step-father, one to the Department of Work and Pensions and one to Nicholson's workplace.

    The court hears how Nicholson exchanged messages with Lucy's mother, Stacey White, who text him concerned about her missing daughter.

    The court hears how Nicholson replied to Stacey, in which he reassured her that police would find Lucy and said: "Keep your chin up".

    We return. Prosecutor Mr Mousley says he has completed his examination. Defence barrister James Newton-Price QC will now examine the police analyst.

    Mr Newton-Price refers to the day of July 25, when Mr Nicholson's phone receives an email notification, showing he had received a message from Lucy McHugh and refers to the police's evidence that both logged on to Facebook around 8.50am that day.
    He asks if it is fair to say there was no data showing a message had been sent between the two.
    The analyst replies: "That would be fair."

    Mr Newton-Price probes the police's analyst over the phone data at Tanners Brook.
    He tells the jury there are "jumps" in the location data, showing Nicholson's phone near an area of vegetation and then a nearby residential road in a matter of seconds.
    Mr Newton-Price tells the court: "In essence, it is fair to say that when in these types of terrain, we say there is a rather more chaotic pattern in terms of location data."

    Mr Newton-Price finishes his questioning. Mr Mousley calls an expert witness, a professor with 50 years of experience in navigation systems and 26 years in GPS navigation.

    The professor tells the court about GPS. He says it is a navigation and positioning system, operated by the US government.

    He says it involves 32 satellites, of which at any point on the surface of the planet, a person is visible by around nine of those.

    He tells a court that a phone acts as a GPS receiver, collecting a signal from those satellites. He says there is a "remarkable" calculations made, which can then mark that device's position.

    He says the Global Navigation Satellite System (GNSS) can be disrupted by tall buildings in cities, as well as being in someone's pocket or a wooded area. He adds that if there are issues with the GNSS, the phone's location could also be found using Wifi Positioning and Cell Sighting.

    The expert says that he agrees with the defence's "scepticism" over the Google Fitness App data.

    But he describes Hampshire Constabulary's use of cloud data in the Lucy McHugh investigation as "groundbreaking" and "very exciting".

    We are about to resume here after lunch. The court will hear more evidence from an expert in the field of navigation and GPS.

    The expert evidence begins to explain Structural Query Language (SQL) data, which the police used in their investigation into Lucy's death.
    He begins talking about "fixes" - essentially the phone trying to find out where it is.

    He tells the court that in one instance, a set of "fixes" from Nicholson's phone on July 25 show him moving along Coxford Road at a speed of around 12mph.

    He says that the phone data, along with longitude and latitude, also showed altitude.
    When he compared the altitude in Nicholson's phone data to the actual altitude in three locations he found it to be accurate to within one and three metres. He said this means that the longitude and latitude can be relied upon as more accurate.

    The expert adds that the time on a phone such as Nicholson's is "incredibly precise".

    He tells the jury that GPS and GNSS can be unreliable, due to events such as solar storms, but said that through investigations he was able to establish that there was no such event on the July 25.

    He tells the court about the Nicholson's phone data showing it located at Nicholson's friend's house on Dunkirk Road.
    He says that around 9.30am until 9.47am on July 25, Nicholson's phone slows the number of "fixes" it makes. He described it as a phone going into a "kind of sleep mode".
    The expert tells the court this is consistent with a phone being still - and uses the example of a phone sitting on a table.

    He adds that the phone made "seven fixes over the next hour".

    Cheers Alyce.

    Doesn't seem to be any smoking gun in the evidence yet.

    Mr Newton-Price asks about a change in the phone's location behaviour around the area of Tanners Brook.
    He asks if that is consistent with the phone entering a wooded area.
    He says "yes".

    The expert says at the time, the phone was slipping from GNSS and into Cell Sighting at this time.

    The jury hears as a result, the accuracy range of the data increase.

    Mr Newton-Price asks if this is a "classic example" of terrain interrupting with the phone's location.
    The expert replies it is more likely to be foliage.

    Mr Newton-Price asks if the court should be "cautious" of making assertions about the data being used to mark a precise location.
    The expert says: "To a variable degree."
